Christopher Chyba
Professor in the Department of Astronomy and Astrophysics at Princeton University. Much of Chyba's current research lies in astrobiology, including the investigation of a putative ocean on Europa from an orbiting spacecraft, water and organic molecules on Mars both past and present (see Mars, water; Mars, life), and the environment of the prebiotic Earth (see Earth, primitive conditions). He earned his Ph.D. at Cornell University under the supervision of Carl Sagan and featured in Time magazine's December 1994 cover story "50 for the future".
