I primarily work in the field of stellar astrophysics, where my current efforts are focused on the physics of white dwarfs and their explosions as Type Ia supernovae. This includes the theoretical study of many different physical phenomena, including thermonuclear instabilities, propagating combustion fronts, detonations and stellar oscillations. I have considered the prospects for detection of coalescing neutron star/neutron star binaries at cosmological distances and accreting neutron stars in our Galaxy with the Laser Interferometer Gravitational Wave Observatory.
Almost all of my current research is involved in understanding the many ways in which stars die and how they manifest themselves to observers. What kinds of compact remnants they leave behind (white dwarfs, neutron stars or black holes) is also of paramount importance.Over the last five years, my research has spread into the studies of accreting white dwarfs and how they respond to surface and interior thermonuclear ignitions, sometimes resulting in Type Ia supernovae. I am also avidly interested in optical transients, some of which will soon be followed up by the Santa Barbara based Las Cumbres Observatory Global Telescope Network.
