Seiji Fujimoto
Assistant Professor, David A. Dunlap Department of Astronomy & Astrophysics
Seiji Fujimoto is an assistant professor in the David A. Dunlap Department of Astronomy & Astrophysics. He grew up in a rural town in Kyoto, Japan and earned his PhD in astronomy from the University of Tokyo. Fujimoto then enjoyed his postdoctoral life as a DAWN Fellow in Copenhagen and a NASA Hubble Fellow in Austin from 2022 to 2025, before joining the University of Toronto in 2025.
As an observational astronomer, Fujimoto’s research focuses on multi-wavelength observations with world-class telescopes to explore what happened in the early universe, particularly during the first billion years after the Big Bang, and how cosmic history has evolved since then. He leads several large astronomical surveys as principal investigator, including one of the largest NASA James Webb Space Telescope programs ever approved, dedicated to studying the first galaxies, black holes, stars and their explosions in the earliest epoch of the universe.
