Simon Blouin

I am a CITA National Fellow in astrophysics at the University of Victoria.

I use a vast array of numerical simulation techniques to build improved physics models of white dwarfs (dead stars). By comparing those models to astronomical observations, I use white dwarfs as accurate cosmic clocks, probes of planetary evolution, and tracers of supernovae. This Physics Today article is a good introduction to the kind of questions I am currently working on.

I hold a PhD in Physics from the Université de Montréal (2019). I was previously a Banting Fellow at the University of Victoria (2021-23) and a Director's Postdoc Fellow at Los Alamos National Lab (2019-21).
