Research

My research addresses fore front problems in stellar death astrophysics through extensive and panchromatic observations of various types of massive stellar explosions, specifically Gamma-Ray Bursts and Supernovae, which are among the most powerful explosions in the universe, as well as a growing class of exotic transients. With the goal of understanding their stellar progenitors and the explosion conditions that determine the fate of massive stars, I also study these stellar explosions' host environments and host galaxies, in particular the metallicities at the explosion sites, as a promising new tool for differentiating between various progenitor models. Astrophysics is entering the Golden Age of innovative time-domain surveys that stand to revolutionize our understanding of the transient sky. I'm part of the very successful and current Palomar Transient Factory (see PTF at http://www.astro.caltech.edu/ptf/ ), as well as the large-scale Large Synoptic Survey Telescope (see LSST at http://www.lsst.org/lsst/) planned for ~2016.
