Shawn Domagal-Goldman in a Research Space Scientist in the Planetary Envioronments Laboratory at NASA’s Goddard Space Flight Center in Greenbelt, MD. He is an astrobiologist, and an expert in 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 that would look for life on exoplanets. Shawn is also an instinctive collaborator, and is a member of many research and mission teams, including the Curiosity science team, the Exo-S Science and Technology Definition Team, the ATLAST Science Team, the LUVOIR Science and Technology Definition Team, and HabEx Science and Technology Definition Team, the NASA Astrobiology Institute’s Virtual Planetary Laboratory, and the Goddard Institute for Space Studies team in the Nexus for Exoplanet Systems Science.
