Curriculum Vitae, Publications (ADS)

I am the current Bart J. Bok Fellow here at Steward Observatory, the Astronomy Department at The University of Arizona. I am also a visiting Scholar at The University of Chicago.

Before coming to Arizona, I was a Research Scientist in the University of Chicago Department of Astronomy and Astrophysics, associated with the Joint Institute for Nuclear Astrophysics (JINA). I also worked and continue to work closely with several people in the Center for Astrophysical Thermonuclear Flashes I received my Ph.D. in Physics in 2004 from The University of California, Santa Barbara under Lars Bildsten. I received my B.S. in Mechanical Engineering, Physics, and Applied Mathematics from Florida State University.

My research interests lie in refining stellar physics via its application to novel and dynamic astrophysical systems. More specifically, I study white dwarf stellar remnants accreting mass from a companion in close stellar binaries. I have calculated the white dwarf's thermal state and seismological characteristics and am currently utilizing these in tandem with observational measurements to derive general properties of the compact stellar binary population. I am also using hydrodynamic simulations to study the explosive nuclear events which occur in accreting white dwarf binaries, including surface runaways (Classical Novae) and thermonuclear supernovae (Type Ia). Type Ia Supernovae are one of the premier probes of the expansion history of the universe. I am working to better understand their origin in mass transferring binaries and how the properties of the binary are related to properties of the explosion outcome observed.
