QTM 110 or QTM 100 
QTM 315: Game Theory I 
From the study of legislatures and courts to the design of electoral systems and regulation, game theory applications are farranging and have become one of the predominant means of modeling and evaluating social interaction in fields as diverse as economics, law, and biology. Game theory insights have also profoundly changed and expanded the use of auctions across industries; auctions and related mechanisms are used to sell online advertising, to allocate resources in the “sharing economy,” to assign contractors to suppliers, and to apportion spectrum to telecommunication companies. Game theorists working on market design have transformed the medical resident matching market, improved school choice procedures, and started novel markets for kidney exchange. Increasingly, firms are adopting game theory tools to improve not only their competitive position via their external relations with customers, competitors, and suppliers, but also their internal markets for resources and talent. This course provides a technical introduction to the noncooperative theory of games and its various tools that analyze strategic interactions. Selected topics include normal and dynamic games, games of incomplete information and repeated games. Applications are drawn from a wide range of disciplines including business, economics, political science, biology, and sociology. 
None 
QTM 345: Advanced Statistics 
This course introduces the workhorse of data analysis: multiple regression. Violations of conditions for valid inference of multiple regressions are demonstrated in the observational data and typical treatments are introduced accordingly. Specifically, the course devotes to endogeneity and heterogeneity problems in social science. We deal with endogeneity problem with instrumental variable methods and simultaneous system. For heterogeneity, we bring in the additional time dimension for panel data models. For all methods, finite sample and large sample properties are studied. 
QTM 220 
QTM 355: Introduction to Time Series Analysis 
This course provides students with a theoretical and practical basis for analyzing complex data sets that depend on time.

Interspersed with explorations of the mathematical underpinnings of these concepts are data analysis practicums using R, providing context to the theoretical ideas that are introduced, as well as a final project that allows students to study a particular problem in depth. Students emerge from this class knowing how to approach noisy realworld data of this type, possessing a broadlygeneralizable toolkit that spans disciplines from economics to astronomy to geology to medicine to ecology. 
QTM 220 
QTM 385: Data Science Computing 
This course exposed students to popular languages for data analysis, important programming and computing concepts useful when working with computers, and emphasizes good workflows for reproducible research using modern tools. It teaches basic Python concepts and syntax. Students primarily write code in Jupyter/IPython notebooks, start with essential computer literacy (e.g. shell commands), and finish with topics such as Numpy for scientific computing, pandas for data science, and cloud computing using notebooks on AWS and google cloud. Emphasis is placed on good work for reproducible research (e.g. data cleaning using scripts versus hacking away at an excel file and leaving no explanation of how you got from original data to clean data). Overall, the emphasis is on learning programming for the sake of using state of the art data science tools, as opposed to programming for the sake of programming.

QTM 385: Social Choice and Electoral Systems 
This course provides students with a rigorous introduction to the field of social choice theory. Social choice concerns the study of preference aggregation: most commonly, taking a collection of individuals with heterogeneous preferences as an input and then examining potential ways in which a collective, or social, preference is constructed. Our goal is to mathematically formalize and axiomatize the properties of different aggregation rules and to characterize rules that yield desirable outcomes. Students master various proof techniques as they work through the major results in this field (Arrow’s theorem, the GibbardSatterthwaite theorem, and the revelation principle, among many others), and learn how these results can be applied to a variety of fields in the social sciences. The course concludes with an introduction to mechanism design, which lies at the intersection of social choice and game theory.

QTM 385: (Adv) Social Network Analysis 
Interest in social network analysis has exploded in the past few years, partly due to the latest advancements in statistical modeling and the rapid availability of network data and partly due to the recognition that many analytical problems can be recast as a network problem. Aiming to examine social connections and interactions from structural perspectives, network analysis has become an essential method and tool for studying a variety of issues in social and natural sciences, such as friendship formation, peer influence, social inequality, career mobility, social marketing, organizational competition, economic development, political alliance, diffusion of innovations, contagion of health outcomes, and even protein interactions, to name only a few. This course covers the major methods to collect, represent, and analyze network data. Selected topics include centrality analysis, positional analysis, clustering analysis, the exponential random graph model for modeling network formations, the stochastic actororiented model for dynamic network analysis, meta network analysis, weighted network analysis, text network analysis, causal analysis of network effects, and social networkbased predictions and interventions. Examples are drawn from a wide range of disciplines including business, economics, education, political science, public health, and sociology. Students learn handson skills to conduct their own research by using popular network packages in R such as “statnet” and “RSiena”.

ENVS 250: Fundamentals of Cartography and GIS 
This course provides an introduction to the study and design of maps and the use of geographic information systems (GIS) as a problemsolving tool for geographic and spatial analysis. Course lectures will focus on fundamental concepts and the applications of GIS, data collection and processing, cartographic design techniques, and trends in geospatial technologies. The Bureau of Labor Statistics has reported that GIS and geospatial skills are in high demand among employers. These skills are particularly important for students interested in pursuing careers in academia, in the government, or in the private sector. Many local and federal governmental agencies, such as the Department of Defense, hire employees with GIS skills. Some large consulting firms also require employees to have mapping and GIS skills. Universities tend to be one of the larger employers of those with GIS skills, as a variety of research projects require employees who can use the program. In addition, many private firms also look to hire people with these skills, including real estate, surveying, oil, and electric companies. Exposure to GIS and cartography programs can be helpful career training for interested students.

PHYS / BIOL 212: Computational Modeling 
Computation is one of the pillars of modern science, in addition to experiment and theory. In this course, various computational modeling methods will be introduced to study specific examples derived from physical, biological, chemical, and social systems. We study how one makes a model, implements it in computer code, and learns from it. We focus on modeling deterministic dynamics, dynamics with randomness, on comparison of mathematical models to data, and, at the end, on high performance computing. · Why a student might want to take the class As was said by the great Leonardo, "He who loves practice without theory is like the sailor who boards ship without a rudder and compass and never knows where he may cast.” Theory nowadays is often equivalent to mathematical models, which one solves using computers. This course will teach you how to formulate mathematical models and how to solve them using computers. Along the way you will learn Python — a flexible computer language that you will be able to use in other applications as well. · What academic fields use the methods / skills taught in this class Essentially any academic field that does mathematical modeling uses methods and skills developed by this elective course. · Examples of how to apply learned skills outside the classroom We will study examples in epidemiological modeling (relevant to a lot of CDC work), in chemical physics (will be of relevance to those developing new materials in chemistry and physics), or physiology (of relevance to those of you who will become doctors or biomedical researchers). You cannot be an effective researcher nowadays without knowing how to solve problems on a computer — and this class will give you these skills. *PHYS 151 requirement may be waived if student has taken QTM 120, 210, 220, and one class that exposes him/her to how mathematics is used to represent natural phenomena (like Game Theory).
