General

I am a professor of mathematics at Bridgewater State University. Before coming to BSU, I was a postdoc at Cornell University, and before that I was at the University of Southern California where I received my PhD under the direction of Jason Fulman.

Additional information can be found in my CV.

Teaching

For the Fall 2025 semester, I am teaching MATH 202 (Linear Algebra), MATH 403 (Probability Theory), MATH 625 (Complex Analysis), and MATH 650 (Probability).

Research

My research is primarily concerned with probability theory and its applications. I am particularly interested in Markov chains defined on algebraic and combinatorial structures and in distributional approximation using Stein's method techniques.

Probability Notes

You are also welcome to look at my old notes for Basic Probability, Probability Theory I, Probability Theory II, and Random Walks & Representations.

Algebraic aspects of the latter are developed more fully in these notes on Representations of Finite Groups.
