Research Interests


Dr. Geronimo Villanueva is a planetary scientist at NASA-Goddard Space Flight Center who specializes in the search for organic molecules on Mars and on icy bodies. He is the Principal Investigator (PI) of the Planetary Spectrum Generator (PSG), Co-PI of the Comet Interceptor Mission, Co-Investigator of the ExoMars/TGO mission, and leader for Mars and Ocean Worlds studies (GTO) for the James Webb Space Telescope (JWST). He also serves as Science and Management advisor to several observatories, including Keck, NASA-IRTF and ALMA. In recognition to his work on small bodies, the International Astronomical Union (IAU) named minor planet '9724' after Dr. Villanueva, while the American Astronomical Society (AAS) in 2015 honored him with the Urey Prize (young planetary scientist of the year).
 
Since completing his Ph.D. studies at the Max-Planck-Institute for Solar-System Research in Germany in 2004, Dr. Villanueva has participated in many projects at three space agencies, NASA, ESA (European Space Agency) and DLR (German Aerospace Agency), with a broad range of research experience in planetary, exploration and Space sciences. He is a strong advocate for Space Exploration and Astronomy, participating in numerous public outreach activities, and chosen as Science communicator by the US State Department and Shakira's foundation 'Pies Descalzos' to promote science in developing regions.
