Welcome to my website!

I am starting as an Assistant Professor in Mathematics and Computer Science at the Massachusetts College of Liberal Arts this fall semester (Fall 2026). Previously, I was a Visiting Assistant Professor in the Department of Computer Science at Williams College.

Research contains an overview of my research and results are found at Publications. I routinely discuss my results at conferences and seminars, listed Presentations. Teaching contains course descriptions from the courses I have taught. Visit the About Me page to learn more.
