About Me

I am currently a Physics PhD candidate at McGill University in the Trottier Space Institute. My research interests lie in the study of Fast Radio Bursts (FRBs) and pulsars through the development of new radio telescopes and detection algorithms. I am a member of the CHIME/FRB Collaboration, with Vicky Kaspi as my advisor. For my PhD program, I am building hardware and software to enable milliarcsecond localizations of FRBs using the CHIME/FRB Outrigger telescopes. After the telescopes are commissioned, I will be using these localizations to learn more about the surrounding environments of FRB sources through follow-up of their host galaxies with multiwavelength observations.

In 2021, I completed my Physics MSc thesis at McGill University on FRB flux calibration using the CHIME radio telescope. Before that, I graduated from the University of Virginia (UVA) in May 2018 with bachelors degrees in both Astrophysics and Computer Science. For my senior thesis at UVA, I worked with Scott Ransom to extend the PRESTO binary pulsar search software to account for orbital ``jerk''.

I love talking about all things related to FRBs, pulsar detection algorithms, and radio interferometry!
