I am an astrophysicist working on progenitors of supernovae, and other transient phenomena related to interacting stars (anything that erupts, explodes, or merges)!

I work in binary star evolution theory and make predictions for the types of binary star systems that can blow up as Type Ia supernovae, how often they occur, and where/when they would explode.

I have been awarded a Future Fellowship by the Australian Research Council in the school of Physical, Environmental, and Mathematical Sciences (PEMS) at the University of New South Wales Canberra (UNSW Canberra), Australia.

At UNSW Canberra I’m working on connecting different types of thermonuclear explosions to their progenitor stars (e.g. age of star when it exploded, how massive it was, what its companion star looked like). Many interacting binary stars that do not make supernovae will produce other interesting transients such as R Coronae Borealis stars, AM CVn binaries, novae, or they may instead collapse to form a neutron star (accretion-induced collapse). I am interested in all of these objects, too, and the various elements they synthesise. I will be looking to hire graduate students in the near future, so please send me a message (via contact form, or just plain email) if you would like to enquire!

From April 2014 to October 2017 I was a postdoctoral fellow at the Research School of Astronomy and Astrophysics (Mount Stromlo), at the Australian National University (most of the time I was funded by CAASTRO).
Before that, I was a postdoctoral fellow at the Max Planck Institute for Astrophysics in Garching, Germany (2009 to 2014).
I received my PhD in 2009 from New Mexico State University in Las Cruces, New Mexico, USA. I spent the last year of my PhD at the Harvard-Smithsonian Center for Astrophysics in Cambridge, Mass, USA.
Pre-PhD, I received my Masters from Saint Mary’s University in Halifax, Nova Scotia, Canada, and my Bachelors degree from York University in Toronto, Canada.
