I received my Ph.D. from Ohio State University in 2008, with Herb Clemens; after that, I was a postdoc at the University of Illinois at Chicago and at Kavli IPMU near Tokyo. Since 2012, I have been at Stony Brook University. In the past, I was partially supported by a Centennial Fellowship from the American Mathematical Society, and by a Simons Fellowship from the Simons Foundation.
I am a member of the algebraic geometry group, and I study the geometry and topology of complex algebraic varieties. My research focuses on Hodge theory, and on applications of mixed Hodge modules in algebraic geometry.
This semester, I am teaching MAT 331 (Computer-Assisted Mathematical Problem Solving) and MAT 545 (Complex Geometry).

Claude Sabbah and I are adapting Saito's theory of mixed Hodge modules to the case of complex coefficients. A collection of notes (in progress) can be found on Claude's website.
