Patrick Kelly

Patrick Kelly is an Associate Professor in the School of Physics and Astronomy at the University of Minnesota, where he also serves as the MIfA Director of Graduate Studies. His office is located in John T. Tate Hall in Minneapolis.

Dr. Kelly's research focuses on Supernova explosions, Gravitational lensing, SN host-galaxy environments, SN Ia cosmology, Stellar populations, Star formation, and Dark matter. His work has established him as a leading expert in using gravitational lensing to study distant supernovae and magnified stars. The fingerprint analysis of his research outputs shows strong emphasis on Supernovae Physics (100%), Lensing Keyphrases (63%), Galaxy Clusters Physics (58%), and Galaxies Keyphrases (53%).

His recent publications reveal a strong trend toward utilizing the James Webb Space Telescope for groundbreaking discoveries in gravitational lensing and supernova cosmology. His team has identified more than 40 gravitationally magnified stars in distant galaxies and made the first measurement of the Hubble constant from a multiply imaged Type Ia Supernova using JWST data. His research bridges observational astronomy with cosmological theory, particularly in understanding dark matter distribution through lensing phenomena.

Dr. Kelly leads multiple significant research projects including:

• Early Stars -- Properties of Lenses Stars at z~7 (NASA, 2025-2028)
• Reanalysis of the Core-Collapse Supernova Rate at Cosmic Noon in the Archival HST Imaging (NASA, 2025-2028)
• SNAP Survey for Strongly Lensed Supernovae and Magnified Stars (NASA, 2025-2028)
• Using TURBO to Resolve Shock Breakout from Supernovae (NSF, 2024-2027)

He is an active member of the LSST Dark Energy Science Collaboration and WFIRST Science Investigation Team, contributing to major cosmological surveys. His research has been widely recognized, with numerous publications receiving significant attention across news outlets, social media, and academic platforms.
