This course provides an overview of the science related to observing and understanding sea-level rise, which has a profound impact on the sustainability of coastal cities and ecosystems. In modern research, sea-level rise is viewed as a complex response of the Earth “system of systems” to climate change. Measuring ongoing sea-level change is challenging due to the great natural variability of sea level on short time scales caused by tides, weather, and ocean currents. Interpreting measurements so that one can assess (and mitigate against) potential economic and societal impacts of sea-level rise is crucial but can be complicated, since so many Earth-system processes play a role. Some of these processes are related and others are unrelated to climate change; some of the latter are natural and others are of anthropogenic origin. Students enrolled in this course will through lectures and class discussions address topics related to the underlying observational basis for sea-level rise. Given the complexity of sea level rise, it is important for those in technical positions to understand the systems level interactions that not only lead to rising waters but also the consequences that these changes inflict on other parts of our environment. What we hear most commonly is that sea level rise will affect hundreds of millions of people living in coastal areas and make those populations susceptible to flooding. But in addition to this community effect, sea level rise also have dramatic effects on coastal habitats, leading to issue such as erosion, soil contamination, and wetland flooding, just to name a few. This course will introduce and prepare students to develop a more comprehensive and holistic approach to sea level rise. By training students to observe, measure, interpret, and begin to predict how sea level rise affects populations and communities differently, students will be in strong positions to address, mitigate, and adapt to the challenges more effectively using evidence-based approaches.
Prerequisites: BIOL UN2005 and BIOL UN2006 or the equivalent. General genetics course focused on basic principles of transmission genetics and the application of genetic approaches to the study of biological function. Principles will be illustrated using classical and contemporary examples from prokaryote and eukaryote organisms, and the experimental discoveries at their foundation will be featured. Applications will include genetic approaches to studying animal development and human diseases. All students must get permission from the instructor to be added from the waitlist.
The field of disaster research is relatively new in the United States, as a specific field of study, with the first disaster research center being founded in the early 1960s. The field itself is now highly multi-disciplinary, drawing from the social sciences, anthropology, political science, computer science, engineering, earth sciences, psychology, and medicine and public health. These academic fields have intersected with the practice community by informing holistic emergency planning for all members of a community. Furthermore, these research outputs have informed federal and state policy, the private sector, and community organizations to inform program design and implementation. Translating research into practice remains a constant challenge in this rapidly evolving field. The methodological approaches to disaster research are just as diverse and have become increasingly complex with the advent of big data, the ubiquity of spatial information, and novel cross-disciplinary research. As a new era of compound and cascading disasters has triggered a constant “response” mode within the field of emergency management, the need for practitioners and research with a fluency in research and evaluation methods is required to critically evaluate or generate high quality and ethically based research.
This course provides an introduction to computer-based models for decision-making. The emphasis is on models that are widely used in diverse industries and functional areas, including finance, accounting, operations, and marketing. Applications will include advertising planning, revenue management, asset-liability management, environmental policy modeling, portfolio optimization, and corporate risk management, among others. The applicability and usage of computer-based models have increased dramatically in recent years, due to the extraordinary improvements in computer, information and communication technologies, including not just hardware but also model-solution techniques and user interfaces. Twenty years ago working with a model meant using an expensive mainframe computer, learning a complex programming language, and struggling to compile data by hand; the entire process was clearly marked “experts only.” The rise of personal computers, friendly interfaces (such as spreadsheets), and large databases has made modeling far more accessible to managers. Information has come to be recognized as a critical resource, and models play a key role in deploying this resource, in organizing and structuring information so that it can be used productively.
The climate crisis is a defining feature of contemporary life. How did we get here? This course considers the historical, social, ethical, and political life of global warming in an effort to better understand the present climate age. Themes and topics include: the origins of fossil fuel-based energy systems and the cultural life of oil; the history of climate science and the geopolitics of climate knowledge production; the emergence of climate change as a global political issue; debates about political responses to climate change versus market-based approaches; the question of culpability and who should be held responsible for causing global warming; and the recent emergence of a global climate justice movement and its relationship to racial justice and indigenous rights movements.
Global greenhouse gas (GHG) emissions are now at a record high, and the world’s scientific community agrees that continued unabated release of greenhouse gases will have catastrophic consequences. Many efforts to curb greenhouse gas emissions, both public and private, have been underway for decades, yet it is now clear that collectively these efforts are failing, and that far more concerted efforts are necessary. In December 2015, the world’s nations agreed in Paris to take actions to limit the future increase in global temperatures well below to 2°C, while pursuing efforts to limit the temperature increase even further to 1.5°C. Achieving this goal will require mitigation of greenhouse gas emissions from all sectors, both public and private. Critical to any attempt to mitigate greenhouse gas emissions is a clear, accurate understanding of the sources and levels of greenhouse gas emissions. This course will address all facets of greenhouse gas emissions accounting and reporting and will provide students with tangible skills needed to direct such efforts in the future.
Students in this course will gain hands-on experience designing and executing greenhouse gas emissions inventories for companies, financial institutions and governments employing all necessary skills including the identification of analysis boundaries, data collection, calculation of emissions levels, and reporting of results. In-class workshops and exercises will complement papers and group assignments. A key component of this course will be critical evaluation of both existing accounting and reporting standards as well as GHG emissions reduction target setting practices.
This course will introduce many of the challenges facing carbon accounting practitioners and will require students to recommend solutions to these challenges derived through critical analysis. Classes will examine current examples of greenhouse gas reporting efforts and will allow students the opportunity to recommend improved calculation and reporting methods.
This graduate-level course surveys the many components that go into climate risk assessment, with an emphasis on climate impacts and vulnerability. We will survey the latest research on climate hazards, with an emphasis on the types of extreme weather events that have the largest societal impacts. We will then explore these impacts in detail, by sector and system. We will next investigate determinants of vulnerability, and how vulnerability magnifies climate impacts. We then query how climate solutions can be integrated into risk assessments in a recursive manner. Throughout the course, we will strike a balance between foundational (‘IPCC-type’) examples on the one hand, and emerging topics like compound extreme events and existential risk on the other. Throughout the course we will study and employ a number of risk assessment methodologies, based on case studies from within the private, public, and non-profit sectors.
This seminar class will give an overview of the current knowledge of extreme weather events and the impact of anthropogenic climate change on their characteristics. We will start the course by defining extreme weather events and the current state-of-the-art knowledge of how anthropogenic activities influence them, including trends, detection and attribution, as well as future projections. We will discuss the methods typically used for analyzing extreme events and what are the existing uncertainties. The existing warning systems and forecasts for extreme events will be briefly discussed, including their communication and impacts and possible mitigation measures.
Survey research has played a pivotal role in politics for the better part of the last century, with a wide range of campaign and public policy professionals conducting surveys to gain insight into the thoughts, feelings, and opinions of the electorate and citizenry as a whole. Since the early 2000s, the use of survey experiments has become exponentially more prevalent in the political realm as a way to assess attitudes, anticipate reactions, or measure causal relationships. Recent trends point to the growing importance of the internet and social media to conduct surveys and the linkage of survey data with the wealth of publicly available personal information as well as with information on individuals’ social and economic behavior. In this course, students will learn about the strengths and weaknesses of survey research as well as limitations associated with survey design and various analytical techniques, and they will acquire concrete knowledge of practical tools used in campaigns, advocacy, and election forecasting. Students will be introduced to a set of principles for conducting survey research and analyzing survey data that are the basis for standard practice in the field. Students will be familiarized with terminology and concepts associated with survey questionnaire design, sampling, data collection and aggregation, and survey data analysis to gain insights and to test hypotheses about the nature of human and social behavior and interaction. The course will present a framework that will enable students to evaluate the influence of different sources of error on the quality of data.
Prerequisites: BUSI PS5001 Intro to Finance and BUSI PS5003 Corporate Finance or Professor Approval required. If you have not taken PS5001 or PS5003 at Columbia University, please contact the course instructor for approval. Students will learn about the valuation of publicly traded equity securities. By the end of the semester students will be able to perform fundamental analysis (bottoms-up, firm-level, business and financial analysis), prepare pro forma financial statements, estimate free cash flows and apply valuation models.
Environmental, social and governance issues (‘ESG’) are moving to center stage for corporate boards and executive teams. This elective course complements management and operations courses by focusing on the perspective and roles of the board and C-suite of corporations, financial institutions and professional firms in addressing ESG risks as well as promoting and overseeing governance aligned with ESG principles. The course focuses on the interchange between the external legal, competitive, societal, environmental and policy ‘ecosystems’ corporations face (which vary around the world) and a company’s internal structure, operations and pressures. We will use the United Nations Guiding Principles on Business and Human Rights and the UN Global Compact Principles (which incorporate all aspects of ESG) as the central frameworks to explore the concept of a corporation’s responsibility to respect and remedy human rights and environmental harms. We will also examine the Equator Principles and other frameworks that spell out good practices for project finance and other investment decisions, and reference a wide range of the myriad indices, supplier disclosure portals and benchmarks that exist in this inter-disciplinary field. Relevant regulations, corporate law regimes and court cases will be discussed from the point of view of what business managers need to know. While most of the course will deal with companies and firms serving global, regional or national markets, several examples will deal with the question of how the ESG ecosystem affects or offers opportunities to start-ups.
Globally, over 2 billion people are suffering from moderate-to-severe food insecurity and the Sudan famine being the first famine declared in 2025 since 2020. One key aspect to understanding food insecurity is its spatial distribution and trends that contribute to how food secure a population is. This course will teach students how to collect and analyze spatial data related to food security, as well as touch on important topics in food insecurity. The course will focus on taking real-life food security questions and applying spatial analysis techniques to these questions. In the course, we will cover an introduction to spatial analysis, natural experiments in geography, applying remote sensing to food insecurity, climate shocks and food security, and seasonal forecasting and food security.
This class will have a lecture aspect, which will mainly focus on topics in food security and how they relate to data collection, and a lab section, which will be an opportunity for students to collect data directly, clean the data, and analyze the data using the R programming language with spatial research methods. Example topics in class will be climate variability and food insecurity, policies that can successfully address food insecurity, and understanding spatial aggregation in food security statistics and how that can influence interpretation. These topics will then be further explored in the lab section of the class: specifically focusing on downloading weather data for time series analysis, using a convergence of datasets to map hotspots, and investigating how survey data intersects with spatial datasets.
Publicly traded companies are increasingly challenged to contribute to sustainable development and improve quality of life for everyone. The years ahead will reveal the negative side effects and blind spots of conventional strategy tools, which often focus on short-termism, profit maximization, and share price. Historically, social expectations of businesses have been limited to the creation of wealth for owners and shareholders as well as the creation of jobs and economic development for the communities in which they operate. This limited set of expectations has allowed managers to focus on profit maximization as their primary objective and source of value creation.
Transformative business models, however, will become increasingly important as businesses face the challenges of climate change, resource scarcity and social inequity that dominate today’s competitive business landscape. Acquiring the skills to help navigate these conditions will be essential to businesses that seek to thrive and foster a more sustainable world and create shared stakeholder value.
This course will explore the fundamental role of business in contributing to a more sustainable and just world and the emerging strategies companies are using to align business value creation with social and environmental impacts. How corporations successfully balance the expectations and interests of stakeholders with profit maximization will be explored. This course will also identify the impacts, risks, and opportunities that leadership must assess and develop strategies to address. The course will explore the benefits of ESG/Sustainability in business, how for-profit businesses can thrive in a competitive setting while still creating long-term stakeholder value, and how companies have embedded ESG strategies, plans and programs to address their related challenges and opportunities. In addition, the course will consider business drivers and macro forces that inform ESG strategy and key concepts and tools that are essential to developing value generating ESG strategies that are good for people, planet, and enterprise profitability.
This course gives students visibility into the rapidly changing communication industry and the wide range of careers available. Curated site visits take us inside world-class agencies and corporate/nonprofit organizations to see how they use strategic communication in the real world. Students gain firsthand exposure to leading practitioners while learning the dynamics of collaboration between internal and external stakeholders. Relevant coursework provides additional perspective.
Negotiation today requires navigating complexity, interpreting incomplete data, managing uncertainty, and fostering trust in environments where clarity is scarce and stakes are high. Practitioners must address information gaps and asymmetry, regulatory pressures, and power dynamics while aligning diverse interests and shaping agreements that endure.
This course prepares students with skills to negotiate effectively across healthcare, technology, and business—domains where outcomes hinge on data limitations, contractual nuance, and shifting stakeholder priorities. Trust and credibility are emphasized as essential currencies, especially when agreements depend on long-term relationships, compliance, and cross-functional collaboration.
Guest speakers from multiple industries will share practical insights into negotiating across roles and power structures. Their perspectives will underscore the value of preparation, trust-building, and adaptive strategies for navigating uncertainty in dynamic environments.
Students will:
Build and apply negotiation frameworks in complex, multiparty environments.
Learn how to extract meaning from structured (quantitative) and unstructured (qualitative) data.
Develop data-informed narratives to guide decision-making and stakeholder alignment.
Practice identifying cognitive bias, ethical tension, and strategic leverage points.
Engage in simulations and case studies grounded in real-world contracting and influence challenges.
Note for NECR Students
: As an elective offered by the Negotiation and Conflict Resolution (NECR) program, this course builds on students’ conflict negotiation skills (PS5105) and their application in healthcare. Students will further engage with concepts on the influences and cultural understandings of conflict parties, and conflict analysis (PS5124 and 6050). The aforementioned courses will contribute to the understanding of this course’s content and should, in general, be taken before this elective.
This course gives students two credits of academic credit for the work they perform in such an social science oriented internships.
Many environmental and sustainability science issues have a spatial, location-based component. Increasingly available spatial data allow location-specific analysis and solutions to problems and understanding issues. As result, analyzing and identifying successful and sustainable solutions for these issues often requires the use of spatial analysis and tools. This course introduces common spatial data types and fundamental methods to organize, visualize and analyze those data using Geographic Information Systems (GIS). Through a combination of lectures and practical computer activities the students will learn and practice fundamental GIS and spatial analysis methods using typical sustainable science case studies and scenarios. A key objective of this course is to provide students with essential GIS skills that will aid them in their professional career and to offer an overview of current GIS applications. In the first part, the course will cover basic spatial data types and GIS concepts. The students will apply those techniques by analyzing potential impacts of storms on New York City as part of a guided case study. A mid-term report describing this case study and the results is required. In the second part, building on the basic concepts introduced in the first part, students will be asked to identify a sustainable science question of their choice that they would like to address as a final project. Together with the instructor they will be developing a strategy of analyzing and presenting related spatial data. While the students are working on their projects additional GIS method and spatial analysis concepts will be covered in class. At the end of the course Students will briefly present their final project and submit a paper describing their project. This course does not assume that students have had any previous experience with GIS.
This seminar offers participants the opportunity to listen to practitioners discuss a range of important topics in the financial industry. Topics may include portfolio optimization, exotic derivatives, high frequency analysis of data and numerical methods. While most talks require knowledge of mathematical methods in finance, some talks are accessible to a more general audience.
This practicum course is meant to offer valuable training to students. Specifically, this practicum will mimicthe typical conditions that students would face in an internship in a large data-intense institution. Thepracticum will focus on four core elements involved in most internships: (1) Developing the intuition andskills to properly scope ambiguous project ideas; (2) practicing organizing and accessing a variety oflarge-scale data sources and formats; (3) conducting basic and advanced analysis of big data; and (4)communicating and “productizing” results and findings from the earlier steps, in things like dashboards,reports, interactive graphics, or apps. The practicum will also give students time to reflect on their work, andhow it would best translate into corporate, non-profit, start-up and other contexts.
Introducing students to a series of methods, methodological discussions, and questions relevant to the focus of the Masters program: urban sociology and the public interest. Three methodological perspectives will frame discussions: analytical sociology, small-n methods, and actor-network theory.
Nearly all subdisciplines in climate now rely on aspects of data science to understand problems and evaluate solutions. Climate science is generating “big data” including petabytes of observations from sources such as NASA and even more from climate models. With this big, complex data burden comes the need for advanced data science techniques such that scientists can better understand our climate system and explore possible solutions to the challenge of climate change.
This course is a broad introduction to research computing and data science drawing from examples in climate science. Students will learn how to work with, analyze, and visualize big datasets. The course will utilize the scientific python ecosystem, Unix/Linux, shell scripting, terminal commands, git/github, and other techniques.

The ability of many emerging market and developing economy (EMDE) countries to meet their climate financing objectives depends to a large extent on their cost of capital, which in turn is impacted by the actual and perceived risks of their sovereign debt. According to the Jubilee Report published in June 2025 by the Pontifical Academy of Social Sciences and the Columbia University Initiative for Policy Dialogue, 54 countries spend over ten percent of their revenues on interest payments, and 3.3 billion people live in countries that spend more on interest than healthcare. EMDE countries need workable tools to reduce financing costs and manage sovereign debt in order to fund their development needs and to achieve the climate objectives set out in their nationally determined contributions under the Paris Agreement.
This course will explore the roots of the problem, including the pro-cyclical nature of sovereign financing and refinancing; the role of international financial institutions and credit rating agencies; and the main obstacles to resolving sovereign debt distress in an orderly and timely way, contrasting resolution tools for sovereign debt with those available in the private sector. Drawing on real-world case studies, we will look at structural innovations that could help debottleneck climate finance, and how effective they can be. We will consider several prominent proposals to reorient the global financial architecture, focusing on whether and to what extent they can reduce EMDE funding costs and unlock financing for sustainable development and climate investment.
Students enrolled in the Quantitative Methods in the Social Sciences M.A. program have a number of opportunities for internships with various organizations in New York City. Over the past three years, representatives from a number of different organizations – including ABC News, Pfizer, the Manhattan Psychiatric Center, Merrill Lynch, and the Robert Wood Johnson Foundation – have approached students and faculty in QMSS about the possibility of having QMSS students work as interns. Many of these internships require students to receive some sort of course credit for their work. All internships will be graded on a pass/fail basis.
This course is a core course for all Climate School students in the MA in Climate and Society and MS in Climate .5 credits in the fall and 5. credits in the spring. It is a practicum-style course focused on the application of classroom learnings in a range of professional and real-world situations.
At the beginning of the fall semesters, students will be grouped in teams and assigned a previous years’ Capstone project (a summer project that former CS students have produced in partnership with an external partner). Students will use this previous capstone project to practice skills including: stakeholder engagement strategies, communication and presentation skills, systems thinking, and project planning.
The fall will be focused on grounding in the topic and challenge of the capstone project, stakeholder discovery and mock engagement, and evaluating its application to the New York City context. The spring will be focused on evaluation of problem definition of the client, work planning and project planning, learning from the client and/or alumni about the outcomes and contemporary challenges/applications of the project, and producing a final project as a team. By the end, students will be prepared to fully engage with their own capstone projects in future semesters, will have honed critical skills to support successful professional applications of their Climate School courses, and will have a ‘mission and values statement’ to guide their future practice as professionals.

This course explores the role of international institutions—including the IMF, World Bank, UN agencies, Multilateral Environmental Agreements, regional development banks, and national development banks—in shaping the global response to climate change. We will analyze how mandates, governance structures, financial instruments, and geopolitical dynamics shape the capacity of these institutions to mobilize and allocate climate finance.
The course emphasizes how current institutions emerged from historical conditions (e.g., the Bretton Woods system, the dollar’s role as anchor currency, and mechanisms to prevent financial instability), and how those legacies both enable and constrain climate finance today. Students will examine reform debates and the rise of new institutions (e.g., AIIB, BRICS’ New Development Bank) as potential complements or alternatives to the prevailing institutions.
Site visits to the IMF and World Bank in Washington, D.C. and the United Nations Headquarters in New York will provide first-hand exposure to the workings of these institutions. The class will also have live video interactions with other global institutions.

Successful leaders in politics, campaign management, and related professions must be able to lead change in their organizations, not only motivate and manage their teams toward a common goal. The aims that leaders seek to achieve are determined by their ability to create value, collaborate, influence, navigate uncertainty, and advance ideas, programs, and movements. In this course, students will learn about how the development of personal attributes and abilities lays the groundwork for building the core leadership competencies that are essential for high-impact management as well as changing the behavior and the culture of organizations with particular emphasis on how to successfully introduce the methods and results of analytics. Students will explore the motivations, obstacles, and interventions of change, and learn to build alliances, facilitate difficult meetings and develop a transformation plan. They will also review some of the most important academic research and business publications on change management and the implementation of analytics. The course is intended to enhance practical skills through dynamic interactions with the instructor, role-playing with classmates, and other real-world experiences.
Fashion’s consistent ranking among the top 3 global polluters has become a decades old fact struggling to gain a proportionate response among the brand startup and sourcing community. With industry revenues set to exceed $1 trillion, there is an opportunity to critically address existing revenue models predicated on traditional metrics, such as constant growth, and singular bottom lines. The course attempts to create a nexus between the fashion entrepreneur and systems thinker to explore strategic solutions that address sustainability though an environmental, social and economic lens. The aim is to foster a mindful, yet critical discourse on fashion industry initiatives, past and present, and to practice various tools that help transition existing organizations and incubate new startups towards sustainable outcomes.
Students in the Master of Science in Sustainability Science program will encounter a range of scientific problems throughout their Science-specific courses that require a strong working knowledge of computer programming. This course provides an introduction to scientific programming using Python. Computer coding skills gained in the course will prepare students for coursework in the Master of Science in Sustainability Science program as well as to succeed in a career having a programming component. Students enrolled in this course will learn through lectures, class discussion, and hands-on exercises that address the following topics:
Basics of computer programming, including precision of variables, arrays and data structures, input/output, control flow, and subroutines.
Applying Python to read common scientific data formats, including NetCDF for gridded climate and other environmental data.
Applying Python for data analysis, with a focus on popular machine learning methods including linear regression, decision trees, neural networks, principal component analysis, and clustering.
Applying Python to visualize scientific data through basic X-Y plots as well as images of data fields on a global map.
This course will train students to analyze and model scientific data using Python in order to better understand current and future environments and their interactions with human systems. By learning analysis and modeling with Python, students will be better able to inform sustainability policy, management, and decision-making.
The course is designed to teach students the foundations of network analysis including how to manipulate, analyze and visualize network data themselves using statistical software. We will focus on using the statistical program R for most of the work. Topics will include measures of network size, density, and tie strength, measures of network diversity, sampling issues, making ego-nets from whole networks, distance, dyads, homophily, balance and transitivity, structural holes, brokerage, measures of centrality (degree, betweenness, closeness, eigenvector, beta/Bonacich), statistical inference using network data, community detection, affiliation/bipartite networks, clustering and small worlds; positions, roles and equivalence; visualization, simulation, and network evolution over time.
This course is designed to the interdisciplinary and emerging field of data science. It will cover techniques and algorithms for creating effective visualizations based on principles from graphic design, visual art, perceptual psychology, and cognitive science to enhance the understanding of complex data. Students will be required to complete several scripting, data analysis and visualization design assignments as well as a final project. Topics include: data and image models, social and interactive visualizations, principles and designs, perception and attention, mapping and cartography, network visualization. Computational methods are emphasized and students will be expected to program in R, Javascript, D3, HTML and CSS and will be expected to submit and peer review work through Github. Students will be expected to write up the results of the project in the form of a conference paper submission.
An introduction to Bayesian statistical methods with applications to the social sciences. Considerable emphasis will be placed on regression modeling and model checking. The primary software used will be Stan, which students do not need to be familiar with in advance. Students in the course will access the Stan library via R, so some experience with R is necessary. Any QMSS student is presumed to have sufficient background. Any non-QMSS students interested in taking this course should have a comparable background to a QMSS student in basic probability. Topics to be covered are a review of calculus and probability, Bayesian principles, prediction and model checking, linear regression models, Bayesian calculations with Stan, hierarchical linear models, nonlinear regression models, missing data, and decision theory.
Social scientists need to engage with natural language processing (NLP) approaches that are found in computer science, engineering, AI, tech and in industry. This course will provide an overview of natural language processing as it is applied in a number of domains. The goal is to gain familiarity with a number of critical topics and techniques that use text as data, and then to see how those NLP techniques can be used to produce social science research and insights. This course will be hands-on, with several large-scale exercises. The course will start with an introduction to Python and associated key NLP packages and github. The course will then cover topics like language modeling; part of speech tagging; parsing; information extraction; tokenizing; topic modeling; machine translation; sentiment analysis; summarization; supervised machine learning; and hidden Markov models. Prerequisites are basic probability and statistics, basic linear algebra and calculus. The course will use Python, and so if students have programmed in at least one software language, that will make it easier to keep up with the course.
Prerequisites: Undergraduate Statistics This course introduces students to basic spatial analytic skills. It covers introductory concepts and tools in Geographic Information Systems (GIS) and database management. As well, the course introduces students to the process of developing and writing an original spatial research project. Topics to be covered include: social theories involving space, place and reflexive relationships; social demography concepts and databases; visualizing social data using geographic information systems; exploratory spatial data analysis of social data and spatially weighted regression models, spatial regression models of social data, and space-time models. Use of open-source software (primarily the R software package) will be taught as well.
This course is intended to provide a detailed tour on how to access, clean, “munge” and organize data, both big and small. (It should also give students a flavor of what would be expected of them in a typical data science interview.) Each week will have simple, moderate and complex examples in class, with code to follow. Students will then practice additional exercises at home. The end point of each project would be to get the data organized and cleaned enough so that it is in a data-frame, ready for subsequent analysis and graphing. Therefore, no analysis or visualization (beyond just basic tables and plots to make sure everything was correctly organized) will be taught; and this will free up substantial time for the “nitty-gritty” of all of this data wrangling.
Prerequisites: basic probability and statistics, basic linear algebra, and calculus This course will provide a comprehensive overview of machine learning as it is applied in a number of domains. Comparisons and contrasts will be drawn between this machine learning approach and more traditional regression-based approaches used in the social sciences. Emphasis will also be placed on opportunities to synthesize these two approaches. The course will start with an introduction to Python, the scikit-learn package and GitHub. After that, there will be some discussion of data exploration, visualization in matplotlib, preprocessing, feature engineering, variable imputation, and feature selection. Supervised learning methods will be considered, including OLS models, linear models for classification, support vector machines, decision trees and random forests, and gradient boosting. Calibration, model evaluation and strategies for dealing with imbalanced datasets, n on-negative matrix factorization, and outlier detection will be considered next. This will be followed by unsupervised techniques: PCA, discriminant analysis, manifold learning, clustering, mixture models, cluster evaluation. Lastly, we will consider neural networks, convolutional neural networks for image classification and recurrent neural networks. This course will primarily us Python. Previous programming experience will be helpful but not requisite. Prerequisites: basic probability and statistics, basic linear algebra, and calculus.
Machine learning algorithms continue to advance in their capacity to predict outcomes and rival human judgment in a variety of settings. This course is designed to offer insight into advanced machine learning models, including Deep Learning, Recurrent Neural Networks, Adversarial Neural Networks, Time Series models and others. Students are expected to have familiarity with using Python, the scikit-learn package, and github. The other half of the course will be devoted to students working in key substantive areas, where advanced machine learning will prove helpful -- areas like computer vision and images, text and natural language processing, and tabular data. Students will be tasked to develop team projects in these areas and they will develop a public portfolio of three (or four) meaningful projects. By the end of the course, students will be able to show their work by launching their models in live REST APIs and web-applications.

Students gain important perspective on leadership styles, mastering the competencies required for a variety of contexts.
From a global perspective, many of the earth’s most important environments and resources for global sustainability are located in marine and estuarine areas. This class will explore open-ocean and estuarine processes, reviewing what is known about the temporal variability and interconnectedness of these physical and biologic systems.. A few examples include; 1.) oceanic environments were incompletely understood processes regulate the exchange of heat, water and carbon dioxide gas with the atmosphere, 2.) the relationship between nutrients and primary production and fisheries in open ocean, estuarine and coral reef environments and climatic phenomenon such as El Niño South Oscillation (ENSO), the Pacific Decadal Oscillation (PDO) and Atlantic Multidecadal Oscillation (AMO). 3.) For estuaries, current sea level and urbanization stresses on the coastal environments will be discussed. Professionals working in the environmental and engineering fields will benefit from a wide-ranging discussion of the multi-scaled processes influencing estuaries. Knowledge of the processes operating in these environments will lead to a more thorough understanding of the complex issues that may influence infrastructure and coastal development in and around estuarine environments in the near-future. Throughout the class we will explore marine and estuarine processes by studying regional and local responses to broader scale climatic forcing. Reading of textbook chapters and journal articles will supplement in-class lectures and discussion. Grading will be based on class participation, a two exams and a research paper. At the end of the course, students will have a strong scientific understanding about the impacts made on marine and estuary systems through physical, chemical, and biological processes. The course will prepare students to be well-trained in the core features of these systems and the relationship between natural and human processes, and equip them with the skills needed to explore marine and estuary systems in diverse scales and functions in the future.
The “Quantum Simulation and Computing Lab” will give students in the Quantum Masters program hands-on experience in quantum optics, quantum simulation and quantum computing.

This is a practice-based course designed to introduce students to ombuds work, and to help students develop the skills, knowledge, and attitudes required to succeed in the role of an organizational ombuds. Underlying theory will be explored in the context of practice. This course will emphasize the Standards of Practice and Code of Ethics put forth by the International Ombudsman Association (IOA). Upon successful completion of the course, students will be fundamentally prepared to apply for entry-level positions in the field of organizational ombuds and should have the requisite knowledge base to sit for the IOA’s Certified Organizational Ombuds Practitioner exam.
Note for NECR Students
: This course is offered as an elective in the Negotiation and Conflict Resolution (NECR) program. The course builds upon students’ negotiation and mediation skills and self-awareness as a practitioner. It is highly recommended that students complete PS5105, PS5107 and PS5124 prior to enrolling in this course.
Complexity of Conflict and Change Management (NECR K5095) is an elective course in the Negotiation and Conflict Resolution (NECR) Program. The course explores how change can create conflict and also how conflict requires change. Conflict is generally about differences in how people think, know, prefer, believe, and understand. By entering into a conflict resolution process, people can shift their understanding and beliefs about the conflict, the other party or parties, and possible outcomes. The course reviews literature and case studies of how people are impacted at a fundamental level when change occurs. Understanding this elemental human experience can lead to greater self-awareness and the ability to manage change professionally and personally, in order to become effective change agents, negotiators, mediators, and peacemakers. We will also explore how leaders at all levels in organizations can play an important role in implementing change in an organizational context. Thoughtful and strategic approaches that consider the impact of a change management process can mitigate and even prevent conflict. We will review change management models and links to developments in neuroscience and how humans are biologically wired to resist change. Balancing theory and practice, this course will focus on the experience and expertise of the students. They will learn to apply practical conflict resolution approaches to change efforts at the individual and organizational levels as well as consider national and international applications.
