Most Saturday afternoons I help at the TAMU Math Circle.


I work in noncommutative and homological algebra. A brief summary is here.
A longer description of my current research program, including work with students and postdocs, is here, while a more condensed version of recent work specifically in cohomology of Hopf algebras is this research report. My past research is described here.
