I use the Athena hydrodynamics code to simulate interstellar gas dynamics. In the course of my research, I have extended Athena's capabilities to include self-gravity with static mesh refinement. This package utilizes the HYPRE linear solver library. I have also implemented several algebraic turbulence models. To learn more about these extensions, please email me.

I received my PhD in astrophysics from the University of North Carolina at Chapel Hill in May 2017, and I am currently a visiting assistant professor of Physics and Astronomy at Hampden-Sydney College. I continue to work with Dr. Fabian Heitsch on theories of star formation. We use computational fluid dynamics to model astrophysical processes. My primary research investigates the origin of our Solar System, with complementary projects in star formation and turbulence.
Our Solar System formed 4.6 billion years ago near other massive stars, including supernovae. I model our formation with fluid dynamics.
Turbulence is the norm in the interstellar medium. It is also difficult to model. I work on analytic methods to improve calculations.
Star formation is a turbulent process regulated by gravity and thermal physics. I simulate star formation in colliding interstellar flows.
Stars form in cold, dense environments. I am part of a collaboration studying pre-stellar chemical processes and signatures.
