Dr. Larry Bradley is an astrophysicist and science software engineer at the Space Telescope Science Institute (STScI). He serves as the branch deputy of the Data Analysis Tools Branch and the James Webb Space Telescope Data Analysis Lead at STScI.

His research interests are in the field of observational extragalactic astronomy, focusing on the formation and evolution of galaxies in the very early universe. He primarily uses the James Webb and Hubble Space Telescopes to discover and study high-redshift Lyman-break galaxies, including those gravitationally lensed by massive galaxy clusters.

He is a member of the JWST Cosmic Spring and JWST Prime Extragalactic Areas for Reionization and Lensing Science (PEARLS) science teams. He also serves as the Deputy Principal Investigator of the Reionization Lensing Cluster Survey (RELICS), a Hubble Space Telescope Treasury program. He is also a member of the Cluster Lensing and Supernova survey with Hubble (CLASH), Brightest of Reionizing Galaxies (BoRG), and Hubble Advanced Camera for Surveys (ACS) Science teams as well as a science advisor to the Hubble Frontier Fields program.

JWST Cosmic Spring

JWST Cosmic Spring

Cosmic Spring is using JWST to study distant galaxies in the early universe magnified by gravitational lensing, revealing tiny details we've never seen before.

PEARLS

JWST PEARLS

PEARLS (Prime Extragalactic Areas for Reionization and Lensing Science) is a JWST program to study the epoch of galaxy assembly, AGN growth, and First Light.

RELICS

RELICS

RELICS (Reionization Lensing Cluster Survey) is a large Hubble Space Telescope treasury program to discover some of the best and brightest high-redshift galaxy candidates for follow-up study with current observatories and the James Webb Space Telescope (JWST).

Hubble Frontier Fields

Frontier Fields

The Hubble Space Telescope Frontier Fields is revolutionary deep field observing program to peer deeper into the Universe than ever before and provide a first glimpse of JWST's universe.

CLASH

CLASH

The Cluster Lensing And Supernova survey with Hubble (CLASH) is an innovative survey to place new constraints on the fundamental components of the cosmos using the Hubble Space Telescope.

BoRG

BoRG

The Brightest of Reionizing Galaxies Survey (BoRG) is a large Hubble Space Telescope Program focused on finding rare and bright galaxy candidates at redshifts z >~ 8, when the Universe was less than 650 million years old.
