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**.

I have a dated short (.pdf file, 1.1 page)
and an extended (.pdf file, 28 pages)
versions of the resume.
