about
I am currently an Assistant Professor at the DARK cosmology centre at the University of Copenhagen. Before this, I was a CCAPP Postdoctoral Fellow at the Ohio State University.
My research focuses on understanding the physical processes and observational signatures related to the extreme death of stars, and how these processes influence, and are influenced by their surrounding environment. In particular, I use spaced- and ground- based instruments to study tidal disruption events, black holes, supernovae, and their diffuse and compact objects.
I earned my Ph.D. in Physics and Astronomy from Monash University in 2015 studying the high energy emission from supernova remnants and pulsar wind nebulae. During my Ph.D. I was a Smithsonian Astrophysical Observatory Predoctoral fellow at the Harvard-Smithsonian Center for Astrophysics. I received my Masters of Science from University of Waterloo in 2012, where I was also a Perimeter Scholars International student at the Perimeter Institute for Theoretical Physics. I received a Bachelor of Science with Honours in Physics from Monash University in 2010.
I am from Melbourne, Australia 🇦🇺
