About me

I am a J.L. Doob Research Assistant Professor at the Department of Mathematics at UIUC. My office is in Altgeld 165.

I got my PhD at Northwestern University, and my advisor was Nick Rozenblyum.


My research interests are in algebraic geometry, K-theory and representation theory. In particular, I am interested in the application of Tate objects, homotopical methods and derived algebraic geometry to solve problems in these areas.


  1. Prestacks of Tate type.
  2. Determinant map for the prestack of Tate objects, Selecta Mathematica New Series, 26, 76 (2020), doi:
  3. On the normally ordered tensor product and duality for Tate objects, joint with O. Braunling, M. Groechenig and J. Wolfson, Theory and Applications of Categories 33 (2018), Paper No. 13, 296-349. MR3795418.
  4. Representability of the derived Quot scheme, not submitted.


During the academic year of 2019-2020 I organized the UIUC Algebraic Geometry seminar.


Fall 2020

Math 241H Calculus 3 Honors - all material is accessible on Moodle.

This semester I mentored two IGL projects:
  • Cyclic Vectors for certain D-modules,
  • Higher-Shuffles Operads 2.
