Before coming here, I was at University of Minnesota and MIT. Prior to that, I was a Gibbs Instructor at Yale University and a Postdoctoral Fellow at MSRI. I got my Ph.D. from Harvard University. I did my undergraduate studies at Moscow State University. I went to Moscow High School 57.

I work in Discrete Mathematics. More specifically, my research spans the following topics:

- Discrete and Polyhedral Geometry,
- Enumerative and Algebraic Combinatorics,
- Probability and Computations on Groups.

Here are some of my **papers**. My **Google Scholar profile**.

Here is my book: ** Lectures on Discrete and Polyhedral Geometry**.

- My blog.
- My MO profile.
- My Catalan Numbers Page.
- My What is Combinatorics? quotation page, and a companion "Just combinatorics" quotation page.
- My Collection of Combinatorics videos page (prior to 2015).

- UCLA Combinatorics Seminar
(every Thu 10 am, organized jointly with Pavel Galashin).

See past videos on YouTube. - Los Angeles Combinatorics
and Complexity Seminar (every Tue 9:30 am, organized jointly with Greta Panova).
