I am a topologist, specifically interested in the topology of moduli spaces, in particular configuration spaces and spaces of maps.

More details are in my CV.



I am a postdoc at the University of Copenhagen and can be (occasionally) found in office 772-04-0-11. Søren Galatius is my mentor.


I will be joining Stockholm University in September 2022.
