Puck Rombach

Assistant Professor at the Department of Mathematics and Statistics, University of Vermont.

Graduate Program Coordinator for the MS and PhD in Mathematical Sciences Programs (mathematics track).

My main research interests are in structural and extremal graph theory, probability, and algorithms and complexity. I also enjoy learning about applications of discrete mathematics through interdisciplinary collaborations.

I teach a variety of classes, including combinatorics, graph theory, analysis and algebra.
