Sarah Petersen

I am on the job market looking for a position beginning Fall 2026. 

I am currently a Visiting Assistant Professor at the University of Colorado, Boulder. From January 2023 to May 2025 I was also jointly supported by a  National Science Foundation (NSF) eCHT Reasearch Training Group Postdoctoral Fellowship under the mentorship of Agnès Beaudry (University of Colorado, Boulder). Before that, I spent a semester as a postdoctoral fellow at the Max Planck Institute for Mathematics in Bonn, Germany and received my PhD in Mathematics under the direction of Mark Behrens at the University of Notre Dame in May 2022.

I study invariants in algebraic topology with a focus on computations in equivariant, motivic, and chromatic homotopy theory.  Interest in these invariants arises from the fact they they can often be applied to yield solutions to deep problems in geometry, topology, and algebra.
