Ben Briggs

Hej, I am a Marie Curie postdoctoral fellow at the university of Copenhagen. Previously I was a postdoc in the MSRI complementary program, before that I was a postdoc at the University of Utah, and before that I got my PhD in Toronto in 2018 under Ragnar-Olaf Buchweitz. Here is my CV.

I think about problems in commutative algebra and representation theory, often borrowing ideas from algebraic topology.
