Welcome

I am an astronomer studying transient phenomena associated with the deaths of massive stars and the thermonuclear explosions of white dwarfs. My research focuses on observations of supernovae discovered within days of explosion in order to identify their progenitor stars, constrain the dynamics of the pre-supernova phase, and understand the underlying explosion physics. Research efforts are also devoted to Type Ia supernova cosmology and mapping the peculiar velocity field of our home supercluster, Laniakea. I am also involved in active JWST programs aimed at constraining nucleosynthesis and explosion models of thermonuclear supernovae, as well as studying dust formation in core-collapse supernovae.<\p>
