I am a Research Scientist at NASA Ames Research Center. 


My research interests involve laboratory studies of extraterrestrial materials, especially meteorites and lunar samples, mostly using thermoluminescence and cathodoluminescence.  Other interests include the history of meteoritics and planetary science and educational outreach, I am currently the owner/editor of Meteorite magazine.

My History

Until summer 2011, I was University Professor and W. M. Keck Professor at the University of Arkansas associated with the Arkansas Center for Space and Planetary Sciences (of which I was the founding director), the W. M. Keck Laboratory for Space Simulation and the Department of Chemistry and Biochemistry.  In the past I have performed instrumental neutron activation analysis and electron microprobe analysis.  I have also worked on the surface processes occurring on Mars, asteroids and comets and have developed techniques to investigate these processes using microgravity and space simulation experiments.  For thirty years I taught various chemistry courses at the undergraduate level and nuclear chemistry and cosmochemistry at the graduate level.  Between 1991 and 2001, I was Editor of the research journal Meteoritics and Planetary Science.  As Director of the Arkansas Center for Space and Planetary Sciences I created REU, MS, and PhD programs in space and planetary science. I have published three books and over 150 peer-reviewed research articles.
