About Me

I am a fourth year PhD student in the Department of Astronomy & Astrophysics at the University of Toronto. I work at the Canadian Institute for Theoretical Astrophysics (CITA) with my thesis supervisor Dick Bond and Marcelo Alvarez.

My work focuses on simulating and analyzing the large scale structure of the universe as it evolves from the big bang 13.8 billion years ago until the present day. I work mainly on developing the new parallel implementation of the peak patch picture - a way of efficiently simulating this cosmic evolution. This method allows for the creation of thousands of "mock universes", a computational feat unbeaten by any other modern simulation. The video above is a visualization I created of "flying through" one of these universes!

I have also worked on GPU computing, developing and optimizing algorithms to potentially find fast radio bursts using the CHIME radio telescope, which is currently under construction in Penticton, BC.
