My research is about the connections between symmetry and differential equations. Symmetry can be used to solve differential equations and differtial equations can be used to construct local versions of the representations of symmetry groups.

Within algebraic geometry and representation theory, I study holonomic D-modules related to Sato-Bernstein b-functions, period integrals, and the Knizhnik-Zamolodchikov equations. All of these topics relate to understanding singularities through monodromy.

I also study applications of representation theory to machine learning. I am interested in solving differtial equations by incorporating symmetry into deep learning models using equivariant neural networks. I am also interested in discovering symmetry in data using neural networks.

My current mentors are Jan-Willem van de Meent, Rose Yu, Valerio Toledano Laredo, and Tina Eliassi-Rad. Previously, I was a NSF Postdoctoral Fellow and Zelevinsky Research Instructor in the Math Department at Northeastern University. I was a Ph.D. student of Victor Ginzburg at the University of Chicago until I graduated in 2015.
