Thomas W.-S. Holoien, Ph.D.

I am a Carnegie Fellow at Carnegie Observatories in Pasadena. I completed my Ph.D. in Astronomy in 2017 at The Ohio State University working with Professors Kris Stanek and Chris Kochanek, and I am a core member of the All-Sky Automated Survey for Supernovae (ASAS-SN).

I am primarily interested in leveraging "big data" survey projects like ASAS-SN to study tidal disruption events, supernovae, and other transient events, and in 2014 I was awarded the Department of Energy Computational Science Graduate Fellowship for my work on ASAS-SN. I have also worked with researchers at SLAC National Accelerator Laboratory to develop code for sampling realistic supernovae for a given set of host galaxy properties. For more about my research, please see the research section of my web page.
