About Me

I am a graduate student in the math department at the University of Michigan in Ann Arbor. My advisor is Kartik Prasanna.

Here is a photo of me in front of the statue at Oberwolfach in April 2016.

I am interested in representation theory, number theory, and algebraic geometry.

In the 2017-2018 academic year, I will be supported by a Rackham Predoctoral Fellowship.

Past Updates

I am organizing a learning seminar on Borcherds products with Brandon Carter in Winter 2016.

I will be at Princeton University during Spring 2015.

Publications/Preprints

  1. The cohomology of semi-infinite Deligne-Lusztig varieties

    We prove a 1979 conjecture of Lusztig on the cohomology of semi-infinite Deligne--Lusztig varieties attached to division algebras over local fields. We also prove the two conjectures of Boyarchenko on these varieties.

    Submitted.

    arXiv:1606.01795

  2. Deligne-Lusztig constructions for division algebras and the local Langlands correspondence, II

    We extend the results of arXiv:1406.6122 to arbitrary division algebras over an arbitrary non-Archimedean local field. We show that Lusztig's proposed p-adic analogue of Deligne-Lusztig varieties gives a geometric realization of the local Langlands and Jacquet-Langlands correspondences.

    Submitted.

    arXiv:1505.07185

  3. Deligne-Lusztig constructions for division algebras and the local Langlands correspondence

    We compute a cohomological correspondence between representations proposed by Lusztig in 1979 and show that for quaternion algebras over a local field of positive characteristic, this correspondence agrees with that given by the local Langlands and Jacquet-Langlands correspondences.
