Dr. Campbell received a B.S. in Geophysics in 1986 from Texas A&M University, and a Ph.D. in Geology and Geophysics in 1991 from the University of Hawaii. Since 1992 he has been with the Smithsonian’s Center for Earth and Planetary Studies at the National Air and Space Museum, and is...

Bob Craddock began his career as a geologist at the Center for Earth and Planetary Studies in 1988. He combines remote sensing data, quantitative geomorphic analyses, and terrestrial field investigations to help unravel the early geologic history of Mars and to better understand the processes...

Dr. John A. Grant, III joined the Smithsonian in the fall of 2000 as a Geologist at the Center for Earth and Planetary Studies at the National Air and Space Museum. He is a member of the Science Teams for the Mars Exploration Rovers Spirit and Opportunity, the Mars Science...

Ross Irwin received his bachelor of science in geological sciences from Virginia Tech in 1997 and a PhD in environmental sciences from the University of Virginia in 2005. He completed a post-doctoral appointment at the Center for Earth and Planetary Studies in 2010. For two years he worked for...

Emily is a postdoctoral fellow in the Center for Earth and Planetary Studies studying the ancient tectonic history of Saturn’s moon Enceladus. Reconstructing Enceladus’s early tectonic history will provide insight into how Enceladus developed into one of the few currently geologically active...

Yo Matsubara is a postdoctoral fellow at the Center for Earth and Planetary Studies. She is studying the environment of early Mars using simulation models. Although currently Mars is a very cold and dry planet, it is evident from numerous fluvial features that Mars was episodically warm enough...

Dr. Ted A. Maxwell is Senior Scientist at the National Air and Space Museum's Center for Earth and Planetary Studies. He served as Associate Director for Collections and Research for the Museum from 1996 to 2008, and from 1992 until 1996, he served as the Senior Advisor for Science at the Museum...

Gareth Morgan’s research at the Center for Earth and Planetary Studies (CEPS) focuses on the application of radar to study the geological history of planetary bodies. His lunar and Venus work utilizes data acquired by the Arecibo radar observatory in Puerto Rico to generate radar...

Jennifer assists the Program Manager with CEPS public programs and exhibits. She creates and manages content on special digital displays in the exhibit galleries, as well as designs and produces signage, brochures, handouts, and other related materials. She also manages the museum’s research...

Sharon Wilson joined the Center for Earth and Planetary Studies in 2005 to investigate the geology and geomorphology of landforms on Mars that were formed and (or) modified by surface water. The timing and duration of fluvial processes on Mars provides critical information about the climate...
