welcome to my homepage :)

I'm a 1st year astronomy PhD student at UofT. Thus far, I've primarily done research in radio instrumentation, with a focus on sensitivity characterization and telescope commissioning. I've also dabbled in hydrodynamics simulations with the goal of understanding certain astrophysical transients. Read more about my projects below!

I grew up in Brampton, Ontario, where I attended Turner Fenton Secondary School. I founded its first ever Astronomy Club and have involved myself in astronomy outreach ever since. I did my undergrad at UofT, completing the Astronomy & Physics specialist program alongside a computer science minor and math minor. From my second year onwards, I was an executive of the undergraduate Astronomy Union, responsible for public outreach, student advocacy, and astronomy-related events and initiatives. I first served as its second-year representative, followed by VP of Communications, and finally VP of Operations. I am now the Union's graduate student liaison, and my outreach efforts continue through the Graduate Student Astronomy Association's AstroTours program.

I love teaching, and my career goal is to become a professor. Several years into private tutoring, I snagged my first teaching assistantship, which was for MAT135 during the 2023 fall semester. I followed this up with a couple other TAships including an introductory astrophysics course, AST320 in spring 2025. I will continue to TA throughout grad school, and I consider myself lucky for being able to look forward to this part of academia!

On the other hand, here are the courses I've completed, am currently taking, or plan to take at UofT. Students tend to worry a lot about having a perfect academic record when it comes to grad school applications. I want to show that it's okay to have some stinkers in there too!

I highly recommend visiting the astrophotos and cool stuff sections of this website, as they contain most of the content I've uploaded here. Building this site from scratch has been a project of mine since summer 2023. I update it every month or so. If you notice any bugs or other issues, please contact me.

CHIME Pulsar Calibration on Long Timescales

In summer 2024, with Juan Mena-Parra and Mattias Lazda, I explored how well the location of a pulsar could be constrained using very-long-baseline interferometry with the CHIME + Outriggers telescopes using sub-optimal calibrators. Our motivation was to characterize the system's fast radio burst localization abilities under unideal circumstances.

AREPO Hydrodynamics Simulations for Quasi-periodic Eruptions

I'm working with Chris Matzner, Pavan Vynatheya, and Stephanie Lee on simulations where stars are smashed through black hole accretion disks. We believe that this process may give rise to quasi-periodic eruptions, which are sources on the sky which repeatedly (often irregularly) flare up in the x-ray part of the spectrum. I'll share some cool animations from the many simulations we've run once this work goes public!
