Dr. Yvonne Pendleton

Yvonne Pendleton is no longer the Chief of the Space Science and Astrobiology Division at NASA Ames Research Center. She has moved to Washington D.C. and is working at NASA Headquarters as the Senior Advisor for Research and Analysis for NASA's new Associate Administrator, Alan Stern. Yvonne is an observational astrophysicist. She received her Ph.D. in Astrophysics from the University of California at Santa Cruz in 1987. She is currently investigating the organic component of the interstellar medium and the incorporation of that material into the early solar nebula. The International Astronomical Union named asteroid 7165 Pendleton to honor her pioneering work tracing the evolution and distribution of organic material from stardust to planetesimals. Serving as Science Advisor to the Director of Science at NASA Ames in 2004-5 and as the NASA Ames Astrobiology Academy Director for Research in 2004, she currently leads the Space Science and Astrobiology Division. She has also worked with many education outreach efforts to create high school level curricula for teachers (including Voyages Through Time developed by the SETI Institute) and as a Project Astro volunteer in local Bay Area schools (through the Astronomical Society of the Pacific). Named Mentor of the year in 1996, she continues to devote much of her free time to the encouragement of students at the high school, college, graduate and post graduate levels.
