Picture of me I'm an assistant professor in mathematics at the College of Staten Island, part of the CUNY system. My collaborators include Ioana Dumitriu, Soumik Pal, Chris Hoffman, Hanbaek Lyu, Elliot Paquette, Matt Junge, Larry Goldstein, and Raphaël Lachièze-Rey, Moumanti Podder, David Sivakoff, Fiona Skerman, Leo Rolla, and Erol Peköz.

I study probability and combinatorics. I'm currently teaching Math 214. For more about my research, see my c.v. and my papers below. You can also find all of my papers on my arXiv page.
