Adela (YiYu) Zhang

I'm a Marie Curie postdoctoral fellow at the Centre for Geometry and Topology, University of Copenhagen.

I received my Ph.D. at MIT in July 2023 under the supervision of Jeremy Hahn and Haynes Miller. My thesis examines the interplay between Koszul duality and power operations via the bar spectral sequence. Before that I was an undergrad at MIT. Here is my cv.

I'm interested in stable homotopy theory and its applications to manifold theory, in particular configuration spaces. Most recently I have been working on computations in synthetic and equivariant stable homotopy theory.
