Jean-Marc Perelmuter

Jean-Marc Perelmuter is a Canadian astrophysicist, technology entrepreneur, and author.

Early life and education Perelmuter was born in Rio de Janeiro, Brazil, and later moved to Canada. He completed his undergraduate studies at Beloit College before earning a PhD from Johns Hopkins University. During his graduate studies, he became the first recipient of the Hubble Space Telescope Science Institute's graduate fellowship, where he worked under the mentorship of astronomer Allan Sandage.

Career

Astrophysics research Perelmuter collaborated with Sandage on a series of peer-reviewed studies published in The Astrophysical Journal, investigating the expansion of the universe, observational biases, and cosmic evolution. His research also examined the role of galactic mergers in galaxy evolution. In 1993, he identified the progenitor star of supernova SN1993J, contributing to the understanding of supernova chemistry.

Following his academic work, Perelmuter served as a project manager for NASA's science and education initiatives related to the Messenger mission to Mercury. He later taught physics at the University of Victoria.
