I am an Assistant Professor of Astrostatistics jointly appointed between the Department of Statistical Sciences and the David A. Dunlap Department of Astronomy & Astrophysics at the University of Toronto. I am also an Associate Member of the Dunlap Institute for Astronomy & Astrophysics as well as a Member of the Data Sciences Institute. I am also a member of the SDSS-V, DESI, H3, and S5 collaborations. More information about me can be found on my Personal page.

My research focuses on using a combination of astronomy, statistics, and data science to understand the how galaxies like our own Milky Way form, behave, and evolve over time. This often involves working with massive datasets from wide-field imaging and spectroscopic surveys containing observations ranging from billions of stars and galaxies to interstellar gas and dust.

I co-lead the interdisciplinary Astrostatistics Research Team (ART) along with Gwendolyn Eadie. For more information about the research we do, please check out our homepage!
