He is an astrobiologist that focuses on comparative planetology. As a member of multiple interdisciplinary teams, he simulates the atmospheres of other worlds, including those of ancient Earth, modern Mars, ancient Mars, and exoplanets. He utilizes the outputs from those simulations to interpret data from some of Earth’s most ancient rocks, from the Mars Curiosity rover, and to simulate the capabilities of future space-based telescopes designed to look for life on exoplanets. Shawn is a collaborator by nature, and a member of many research and mission teams, including the Curiosity science team, the HabEx Science and Technology Definition Team, the Large UV-Optical-Infrared Surveyor (LUVOIR) Study Office, is on multiple research teams in the Nexus for Exoplanet Systems Science (NExSS).
