Prof. Joshua Speagle

Josh Speagle is an Assistant Professor of Astrostatistics jointly appointed between the Department of Statistical Sciences and the David A. Dunlap Department of Astronomy & Astrophysics.
His research focuses on trying to use 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. It also is an incredibly collaborative endeavor involving many other faculty members both at the University of Toronto and at other research institutions around the world.
He is also a member of the Data Sciences Institute.
Josh received his B.A. in Astrophysics & Physics from Harvard University in 2015. After spending 2015-2016 working at the Kavli Institute for the Physics and Mathematics of the Universe at the University of Tokyo, he returned to Harvard University in 2016 to continue his graduate studies and received his M.A. and Ph.D. from the Department of Astronomy in 2020.
Before joining the faculty at the University of Toronto in July 2022, he was a Banting & Dunlap Postdoctoral Fellow at the University of Toronto from 2020-2022.
