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

• A1-Euler Characteristic of Low Symmetric Powers and Split Toric Varieties. preprint 2026
• The A1-Euler characteristic of symmetric powers, joint with Jesse Pajwani and Anna Viergever. preprint 2025.
  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.
