Juan Muñoz-Echániz

I am a Research Assistant Professor (postdoc) at the Simons Center for Geometry and Physics at Stony Brook University, mentored by Simon Donaldson. I received my PhD in 2023 at Columbia University, advised by Francesco Lin. My CV.

I am on the academic job market this year.

I am interested in gauge theory, Floer homology, and their applications to topology and geometry. My recent work explores the interplay between gauge theory, mapping class groups of 4-manifolds and complex singularities.
