Hi there! I am currently a NASA Hubble Postdoctoral Fellow at the California Institute of Technology working on supernova progenitor systems and transient astronomy. Fascinated by the final moments of a star’s life before death, I conduct research which focuses on winding back the cosmic clock to understand how certain stars produce the various supernovae observed today. I recently received my PhD in Astrophysics from UC Berkeley where I was a NSF Graduate Research Fellow working with Prof. Raffaella Margutti on the synthesis of multi-wavelength observations (radio to X-ray) supernovae in order to create a complete picture of the final stages of stellar instability and mass-loss before explosion.
