## Research

I work in *noncommutative* and *homological algebra*.

A great introduction to *noncommutative algebra* by Chelsea Walton is here.

Some history and basic ideas of *homological algebra* are in the Wikipedia article
here.

A 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.
