Kevin R. Grazier, Ph.D., is a planetary scientist at NASA’s Jet Propulsion Laboratory (JPL) in Pasadena, Calif., where he holds the dual titles of Investigation Scientist and Science Planning Engineer for the Cassini/Huygens Mission to Saturn and Titan. There he has won numerous JPL- and NASA-wide awards for technical accomplishment. Dr. Grazier holds undergraduate degrees in computer science and geology from Purdue University, and another in physics from Oakland University. He holds an M.S. degree in physics from, again, Purdue, and he did his doctoral work at UCLA. His Ph.D. research involved long-term, large-scale computer simulations of Solar System evolution, dynamics and chaos—research which he continues to this day. Kevin is also currently the science adviser for the PBS animated series “The Zula Patrol” and for the Sci-Fi Channel series “Eureka,” as well as the Peabody Award–winning “Battlestar Galactica.” Commited to astronomical education, Dr. Grazier teaches classes in stellar astronomy, planetary science, cosmology and the search for extraterrestrial life at UCLA, Cal State LA and Santa Monica College. He has served on several NASA educational product review panels, and is also a planetarium lecturer at LA’s landmark Griffith Observatory. He lives in Sylmar, Calif.—and occasionally Mesa, Az.—with a flock of cockatiels and a precocious parrot.
