Curriculum Vitae. (Last updated: 2023 May 16)
Biography
I am a professor in the Astronomy Group within the Department of Physics and Astronomy and I am a core faculty member of The Institute for Advanced Computational Science at SUNY Stony Brook. My research is in the field of nuclear astrophysics, and my work involves simulating
explosive astrophysical phenomena. I have extensive experience with large-scale computing.
Prior to coming to Stony Brook, I had research appointments at the National Center for Supercomputing Applications and the University of Chicago, where I was at the Center for Astrophysical Thermonuclear Flashes. I was also an instructor at the School of the Art Institute in Chicago.
Research Statement
My research is principally in bright stellar explosions known as Type Ia supernovae.
These events produce and disseminate heavy elements and are therefore important for
galactic chemical evolution. Also, the light curves of these events can be standardized
and thereby used as distance indicators for cosmology studies investigating the expansion
history of the Universe. I perform detailed simulations of these events to explore
how factors such as the age or composition of the progenitor affect the brightness
of an event. Understanding such systematic effects is critical to addressing the issue
of the intrinsic scatter of these events, a source of significant uncertainty in cosmological
studies.
