Postdoctoral Research Associate

Ph.D. Planetary Sciences, 2021, Johns Hopkins University

Astrobiology, Exoplanets; Planetary Formation and Evolution, Planetary Astronomy, Planetary Atmospheres, Titan & Outer Solar System

Planetary atmospheric chemistry, aerosols, clouds and hazes

Advisor(s): Mark S. Marley

Dr. Sarah E. Moran joined LPL as the Director's Postdoctoral Fellow in January 2022. She studies planets around other stars, known as exoplanets, and worlds of the outer Solar System. Through laboratory experiments and computer models, she investigates clouds and hazes in planetary atmospheres to figure out how they affect the overall atmosphere, how they alter remote sensing and telescope observations, and how they impact habitability. Sarah also works with observational astronomers, especially through the STARGATE collaboration, to help them interpret her theoretical and experimental cloud and haze results in the context of transiting exoplanet observations. She is also passionate about science communication and science policy.
