## Assistant Professor of Mathematics

## Biography

I have been at Bard since Fall 2016, first as a visiting and now as a tenure-track Assistant Professor in the Mathematics Program. Before that, I was a Visiting Lecturer at Wellesley College (Fall 2013-Spring 2016) and a Visiting Assistant Professor at the Cooper Union for the Advancement of Science and Art (Fall 2011-Spring 2013) in the Albert Nerken School of Engineering. In Summers 2013 and 2014, I was a Visiting Postdoctoral Researcher at the Hebrew University of Jerusalem under the supervision of Gil Kalai. I received my Ph.D. from the Courant Institute of Mathematical Sciences (New York University) in 2011 under Sylvain Cappell as a MacCracken Fellow, and my B.A. in mathematics from Yale University in 2005 after switching from a major in Philosophy at the beginning of my junior year.

## Research

My research is centered on applications of algebraic and geometric topology, with special emphasis on using their methodologies to answer questions in geometric combinatorics and discrete geometry. I am especially interested in mass equipartitions (fair division problems for continuous and discrete measures, generalizing the classical "Ham Sandwich" theorem), as well as generalizations of Tverberg's theorem from convex geometry.
