My research is in geometric group theory and low-dimensional topology. My interests include quasi-isometric classification and rigidity, notions of commensurability, hyperbolic and CAT(0) geometry, boundaries of groups, surfaces and 3-manifolds, Coxeter groups, free-by-cyclic groups, and the study of group splittings.

My Ph.D. adviser was Genevieve Walsh.

At Tufts University, I was the primary instructor for the following courses:
    Math 36, Applied Calculus II (Spring 2014, Fall 2013, Spring 2013)
    Math 34, Calculus II (Summer 2013)
    Math 30, Introduction to Calculus (Fall 2012)

The Math Circle, a program for young students to work on problems in pure math. I instructed Boston-area Math Circle classes 2012-2015.
