Curiouser and curiouser!

I’m a PhD student in Mathematics at Brown University. I’m fortunate to be advised by Melody Chan.

My current research interest is to study enumerative and intersection problems in algebraic geometry, using techniques from combinatorics and representation theory.

Prior to Brown, I was a Lang Fellow at Yale where I received my M.Sc. in math and had spent wonderful four years of undergrad at Harvey Mudd College studying math and music.

I also enjoyed computing and AI. With that, I was lucky to work with amazing research scientists at Google Research during undergrad.

  • Relative Bott-Samelson Varieties
    We recall the definition of relative Bott-Samelson varieties, and prove that the product of two relative Bott-Samelson varieties over the flag bundle is a resolution of singularities of a relative Richardson variety defined with respect to versal flags. This result generalizes Brion's resolution of singularities of Richardson varieties to the relative setting. It also reflects the phenomenon that the local geometry of a relative Richardson variety is completely governed by the two intersecting relative Schubert varieties, studied in Chan-Pflueger 19.

  • Chow ring of Heavy/Light Hassett Spaces via Tropical Geometry
    (with Siddarth Kannan and Dagan Karp, 2019)
    Heavy/light Hassett spaces are moduli space of rational curves with weighted marked points that satisfy a “heavy/light” and a stability condition. We present a computation of the Chow ring of such spaces via Tropical Geometry. Our computation weaves together many beautiful combinatorial gadgets that appear in algebraic geometry. The starting point of our computation is to view these spaces as tropical compactifications of hyperplane arrangement complements, using work by Cavalieri-Hampe-Markwig-Ranganathan. Then the computation of the Chow ring then reduces to intersection theory on the toric variety of the Bergman fan of a graphic matroid. In particular, this reduction allows us to bijectively correspond divisors of the related toric variety to trees with stable weighted rays, thereby computing the final Chow ring combinatorially.
