Biography
Dr. Rose received his PhD from the University of Notre Dame, in South Bend, Indiana, under Prof. Peter Garnavich in 2018. His dissertation was on systematic biases of Type Ia supernova distances used in observational cosmology. As a postdoc, Dr. Rose went to Space Telescope Science Institute (STScI), in Baltimore, Maryland. There he worked as a member of the Roman Space Telescope's supernova science investigation team, lead by Saul Perlmutter. At STScI Dr. Rose worked with Susana Deustua, Andy Fruchter, and many others. In 2020, Dr. Rose moved to Duke University to be a Research Scientist with Dan Scolnic's observational cosmology group. There he continued to be involved in the Nancy Grace Roman mission but also became involved in the Dark Energy Survey, the Vera C. Rubin Observatory, Pantheon+, and several low-z supernova surveys. Finally, he joined Baylor University as an Assistant Professor in the fall of 2023.
