Research Interests

My research interests revolve around Algebraic Geometry.

I am very interested in the problem of compactifying moduli spaces of higher dimensional algebraic varieties, and understanding the geometry of these compactifications. I find it appealing when one can compute explicit numeric invariants of moduli spaces (such as the Brauer group or the Chow ring), or when one can use algebraic geometry to answer questions from combinatorics. Lately I am mainly thinking of constructing a compact moduli space of maps from families of curves to an algebraic stack with a projective good moduli space.

Teaching

I am currently teaching abstract algebra (introduction to group theory). Before at UW I taught linear algebra (math 208).

While at Brown I taught and TA-ed linear algebra, calculus 1, 2 and math 60 (Analytic geometry and calculus).
