Nick Edelen

I am an Associate Professor at Notre Dame. I study problems in geometric analysis and geometric measure theory. Earlier, I was an NSF Fellow and CLE Moore instructor at MIT, under the sponsorshop of Tobias Colding; I was a PhD student at Stanford advised by Simon Brendle and coadvised by Brian White; I was an undergraduate at University of Edinburgh. My email is nedelen at nd dot edu. My office is 283 Hurley.

I am a coorganizer of our Geometry and Analysis seminar.

This fall 2025 I am teaching Calc I. Past teaching

I am currently supported by NSF grant DMS-2506700 and a Simons travel award.
