Class meetings: Wednesdays, 2-5pm Demography Seminar Room
Office hours: by appointment (please send me an email and we can find a time)
This course provides a broad introduction to the empirical and theoretical study of social networks. We will cover classic and contemporary studies, beginning with fundamental definitions and models, and then moving through a range of topics, including models of network formation and structure (homophily, foci, communities); dynamic processes on networks (contagion, influence, and disease models); collaborative networks; personal networks; online networks; and network sampling and data collection. The course material is intended to be of interest to students from a wide range of disciplinary backgrounds, including demography, sociology, statistics, computer science, and related fields.
Please re-check the syllabus before you start each week’s reading; it will be updated as the semester progresses
The requirements of the class are designed to achieve two goals: the first goal is to become familiar with some classic and contemporary research about social networks through reading papers and discussing them; and the second goal is to write a research paper. You should think of the research paper as the first draft of a project that you might be able to continue working on beyond this class.
reading and class participation
Each week, you should read the assigned materials and show up to class prepared to discuss them. One or two of the weeks you will also be in charge of organizing the discussion (possibly with a partner).
For 6 of the class meetings, please write a short response memo (1 to 2 pages). You can pick which weeks you write the memos. These memos should not take an enormous amount of time to write. The main goal of these memos is to help you focus your thoughts about the reading prior to our group discussion; to help us get an understanding of what parts of the reading our discussion should focus on; and to serve as a reference for you in the future. The format of the memos is open, but at a minimum I would like you to be sure to (1) quickly summarize how the readings relate to one another (if you think they do); and (2) briefly describe at least one research idea that the readings generated for you (this could be a single sentence, or the entire memo; it’s up to you).
The response memos are due by noon on the Tuesday before each class.
You will write a short (10-20 pages) research paper to conclude the class. Leading up to the end of the class, you will submit a brief proposal (1 paragraph to 1 page) that describes the paper you plan to work on. The purpose of the proposal is to give you some feedback on the initial idea / data source / etc before you invest a lot of time writing an actual paper. Your final paper should identify an important problem to be studied, briefly review the related literature, describe your proposed research design, and present some (possibly preliminary) empirical findings.
The purpose of this paper is to connect the topics of this class to your actual research, so my hope is that this will be an opportunity to get some feedback on an idea you care about, and that you might continue to pursue beyond class. These proposals are due by Friday, May 4 at 5pm.
NB: Please read each week’s articles in the order they are listed on the syllabus

OPTIONAL: The papers at the end of the syllabus give a good overview of the study of social networks. We won’t explicitly discuss them in class, but they would be helpful to read at some point during the semester.
