1. Verbal Description: This is the first half of the basic graduate course in probability theory. The goal of this course is to understand the basic tools and language of modern probability theory. We will start with the basic concepts of probability theory: random variables, distributions, expectations, variances, independence and convergence of random variables. Then we will cover the following topics: (1) the basic limit theorems (the law of large numbers, the central limit theorem and the large deviation principle); (2) martingales and their applications. If time allows, we will give a brief introduction to Brownian motion.

2. Verbal Description: The essential ideas in the course are (1) systems of linear equations, row reduction and echelon form (2) vectors and matrices, matrix multiplication, invertibility and inverses (3) vector spaces and linear transformations (4) subspaces, linear combinations, spanning sets and bases (5) representing linear transformations as matrices, change of basis (6) kernel and image, row and column rank, Rank-Nullity theorem (7) determinants (8) eigenvalues and eigenvectors (9) finding the eigenvalues of a transformation using the characteristic polynomial (10) finding the eigenspace associated to an eigenvalue (11) inner product spaces and their algebra and geometry, the Cauchy–Schwarz inequality (12) orthogonal projections, Gram–Schmidt, least squares (13) orthogonal and unitary matrices, spectral theory (14) bilinear forms and Jordan form.

4. Verbal Description: This is a graduate course on applied stochastic processes, designed for those graduate students who are going to need to use stochastic processes in their research but do not have the measure-theoretic background. Measure theory is not a prerequisite for this course. However, a basic knowledge of probability theory (Math 461 or its equivalent) is expected, as well as some knowledge of linear algebra and analysis. The goal of this course is a good understanding of basic stochastic processes, in particular discrete-time and continuous-time Markov chains, and their applications to Queueing theory, population biology, Markov Chain Monte Carlo.

6. Verbal Description: Graphs and networks have become an essential part of our daily life due to explosion of data and popularity of social networks. The goal of this course is to introduce and analyze various probabilistic models of random graphs and networks, with an emphasis on heuristics on the big picture and background techniques for rigorous proofs. We will consider models of homogeneous and inhomogeneous random graph, small world (small diameter), and scale-free (power-law degree distribution) networks. Specific topics include: (1) Branching Processes and Probabilistic Methods. (2) Erdos-Renyi Random Graphs and Phase Transitions. (3) Random Graphs with Given Degree Distributions. (4) Proportional Attachment and Scale-Free Models. (5) Small Worlds Models. (6) Random Geometric Graphs and Continuum Percolation.
