**Overview:**

Network structures are pervasive in the world
around us, from the Internet and the power grid, to social acquaintance networks,
to biological networks. This course is intended for graduate students interested in
learning about modern perspectives on networks, and should allow students to incorporate
network theory into their own research. This course will cover *General Techniques* and *Selected Applications*.
**Prerequisites:**

Familiarity with: linear algebra, basic statistics, calculus, ordinary
differential equations, using computer software.

**Course structure:** (1) Lectures, (2) bi-weekly problem sets/paper reviews, and (3) a class project or deeper HW assignments.

(i.e., Everyone does (1) and (2), then for (3) it is either a project or more technical homeworks.)

**Topics:** This course assumes no prior knowledge of networks. We will begin with basic concepts about networks and the mathematical tools for their analysis, developing key metrics for characterizing the structure of a network. We will then examine several models of network growth (random graphs, preferential attachment, small-worlds). Emphasis will then shift to network function and algorithms, such as the Page Rank algorithm for ranking web pages, and also decentralized search and routing in social and information networks. The next topics to be covered will reflect student interest.

**Paper reviews:** For these assignments, you are required to provide a short summary (one or two paragraphs) and a review of the strengths and weaknesses of the paper. The goal of these reviews is to help you synthetize the main ideas and concepts presented in each paper. * Note, not all students will review the same papers. Based on your interests, you will choose the papers.*
**Project:** Students work in **small groups of 5-6 students** on a course project. The projects will complement and extend the lecture material. The project may include simulation and modeling, network visualization, creating software for network analysis, or analysis of a real-world network (such as a transportation, social, biological or ecological network). We will be posting a list of potential project topics.

**Resources:**
There will be no required text for this course. The content will largely come from articles and class notes.
