About Me

I am an applied geometer. Currently, I'm most interested in applying differential geometry, algebraic topology, and representation theory tools to emerging problems in mathematical data science and statistical machine learning.

My research broadly concerns discrete and continuous geometric structures in natural and social sciences. I have worked on scientific problems in marine biology, imaging sciences, evolutionary anthropology, and medical data analysis.
