I work in Operator Algebras. With Bob Powers as my advisor, I received my Ph.D. from the University of Pennsylvania in 2009. My main research interest lies in constructing and classifying E0-semigroups (up to cocycle conjugacy) using the theory of CP-flows and boundary weight maps.

The comparison theory of a particular class of completely positive maps has been central to this research so far. In joint work, I have been working to compute a fundamental invariant (the gauge group) for a family of E0-semigroups, and I have also become interested in various notions of subordination for CP-flows and E0-semigroups.

Here is my CV. You can find a portfolio with some other materials here.

About Me

Born and raised in Louisville, Kentucky, I have been a sports fan my entire coherent life. Most of my family currently resides in Louisville, including eight nephews and a niece (from whom I expect big things).
