Josh Speagle is an Assistant Professor jointly appointed in the Department of Astronomy & Astrophysics and the Department of Statistical Sciences at the University of Toronto. He maintains strong affiliations with the Dunlap Institute for Astronomy & Astrophysics, which forms part of Canada's leading concentration of astronomers at the University of Toronto.
Dr. Speagle received his Ph.D. from Harvard University in 2020, establishing a foundation for his interdisciplinary career at the intersection of astronomy and statistics. His educational background bridges these two critical fields for modern data-intensive astronomy.
His research focuses on astrostatistics and data science with multi-wavelength, large-area surveys, with specific interests in Galactic structure and dynamics; stars and stellar populations; dust and the interstellar medium; galaxy formation and evolution; scalable inference; and Monte Carlo sampling. Dr. Speagle combines astronomy, statistics, and computer science to analyze billions of stars and galaxies from wide-field imaging and spectroscopic surveys to better understand how galaxies like the Milky Way form, behave, and evolve over time.
His recent publications demonstrate a strong emphasis on developing and applying advanced statistical methods to astronomical problems, particularly simulation-based inference, Bayesian methodology, 3D dust mapping, and stellar population analysis. His work frequently leverages major astronomical datasets from Gaia, DESI Legacy Imaging Surveys, and the James Webb Space Telescope.

Dr. Speagle collaborates extensively with researchers across the University of Toronto's three campuses and internationally. His work has significant implications for understanding galactic evolution and developing statistical frameworks for astronomical data analysis. He contributes to the vibrant research environment at the Dunlap Institute, which includes over 50 faculty, postdocs, students, and staff dedicated to innovative technology, groundbreaking research, and world-class training in astronomy.
As a member of the Dunlap Institute community, Dr. Speagle participates in research spanning optical, infrared and radio instrumentation; Dark Energy studies; large-scale structure; the Cosmic Microwave Background; the interstellar medium; galaxy evolution; cosmic magnetism; and time-domain science.
