Kerri Cahoy

Associate Professor of Aeronautics and Astronautics
Primary Appointment - AeroAstro

Kerri Cahoy’ s principal interest is the study of planetary atmospheres for example using spacecraft radio systems to study the atmospheres and ionospheres of solar system planets. An electrical engineer by training, she also designs and builds instrumentation, in particular telescopes equipped with coronagraphs for direct imaging with coronagraphy on spacecraft. Cahoy received her B.S. (2000) in Electrical Engineering from Cornell University, and her M.S. (2002) and Ph.D. (2008) degrees in Electrical Engineering from Stanford University working with the Radio Science Team on Mars Global Surveyor. From 2006 to 2008, she was a Senior Payload and Communication Sciences Engineer at Space Systems Loral in Palo Alto, CA. From 2008 to 2010, Dr. Cahoy was a NASA Postdoctoral Program Fellow in Exoplanet Exploration at NASA Ames Research Center. From 2010 to 2011, she was a Radio Science research scientist on the MIT Gravity Recovery and Interior Laboratory (GRAIL) lunar mission team at NASA Goddard Space Flight Center. Cahoy joined the faculty in 2011.
