## Research

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 E_0-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 E_0-semigroups, and I have also become interested in various notions of subordination for CP-flows and E_0-semigroups.

Here is my CV.

## About Me

Born and raised in Louisville, Kentucky, I have been a sports fan my entire coherent life. Aside of my oldest brother, who is an environmental engineer, I am the only member of my family who does not dislike math. Most of my family currently resides in Louisville, including five nephews (from whom I expect big things) and a noble dog.
