About me:
I am a Clay Research Fellow
at the University of Chicago.
My research
is primarily in algebraic topology and its interactions with algebraic geometry
and algebraic Ktheory.
Here is my
CV.
With Benjamin Antieau, Elden Elmanto, and Maria Yakerson, I am a coorganizer of the electronic algebraic Ktheory seminar.
The Geometric Langlands seminar at UChicago, November 2020 (lecture series by Bhargav Bhatt).
