Hi! I'm Sridhar Venkatesh, a Postdoctoral Research Associate at the University of Utah.
Previously, I was a PhD student at the University of Michigan advised by Mircea Mustaţă and an Assistant Adjunct Professor (Postdoc) at UCLA, mentored by Joaquín Moraga.

Research interests: Algebraic geometry. In particular: higher Du Bois and higher rational singularities, Hodge modules, toric varieties, derived categories.

Here is my CV (last updated: Apr 29, 2026), arXiv, Google Scholar.
