I am an assistant professor at the math department at Bowdoin College. Previously I held postdoc positions at the University of Illinois Urbana Champaign, the Technion, and the Hebrew University of Jerusalem. Before this I was a graduate student at Stony Brook University, with Dennis Sullivan as my advisor.

Research

I study low dimensional topology and geometry. In particular, I am usually thinking about: curves on surfaces, hyperbolic geometry, billiards, translation surfaces and 3-manifolds. During the pandemic, I made some videos for the innovative Nearly Carbon Neutral Geometry and Topology Conferences. Here is a video I made about my work in polygonal billiards. Here is a video I made introducing the topic of translation surfaces of infinite type.

In graduate school, I enjoyed lecturing at the annual Stony Brook Math Summer Camp and designing and teaching geometry/topology courses for the WISE program. I also was a mentor for undergraduate students in the annual summer geometry/topology topology workshop at Stony Brook University, and participated in many department outreach activities. At Stony Brook University, I have been a TA for the following types of courses (some of them many times):

precalculus
integral and differential calculus
mathematical thinking/social choice
analysis
masters courses for teachers: analysis, algebra and geometry
graduate topology
graduate algebraic topology
