I am interested in motivic homotopy theory and quadratically refined enumerative geometry. In the past years, I have been thinking a lot about quadratic Euler characteristics.

Preprints

• The A1-Euler characteristic of symmetric powers, joint with Jesse Pajwani and Anna Viergever.
  This is a survey article written for the conference proceedings of the IAS Park City Mathematics Institute Summer Session on motivic homotopy theory 2024 and based on the talk we gave there.

Published Papers
