Because of the attack on the computer network of the University of Duisburg-Essen, the ESAGA site currently can be reached only at https://www.esaga.net/.... Links pointing to https://www.esaga-uni-due.de/ do not work (but one could manually replace uni-due.de by net), and similarly for content, such as images, at such addresses contained in our pages. (Email messages to @uni-due.de addresses are accepted by our mail servers again.)
We apologize for the inconvenience caused by these problems.

My preferred pronouns are they/them. I'm a postdoc with Marc Levine working primarily on Hermitian K-theory. My areas of interest include (but are not limited to) motivic homotopy theory, higher category theory, equivariant cohomology and derived categories. I'm currently working on an analogue of the Atiyah-Segal completion theorem for Hermitian K-theory, which sits at the intersection of motivic homotopy theory, representation theory and the theory of derived categories of schemes.
