Douglas C. Hamilton received his A.B. in Physics and Mathematics from the 
University of Kansas in 1969 and his Ph.D. in Physics from the 
University of Chicago in 1977.  He served as Research Associate at the 
Laboratory for Astrophysics and Space Research at the University of 
Chicago from 1976-78.  At Chicago he studied the interplanetary 
propagation of solar energetic particles and Jovian electrons using data 
from the Pioneer 10 and Pioneer 11 spacecraft.  

Dr. Hamilton came to the University of Maryland as a postdoc in 1978 and is now
 Professor in the Department of Physics.  His research interests include 
interplanetary particle acceleration and transport processes and the composition
 and dynamics of energetic ions in the magnetospheres of Earth and the outer 
planets.  He has been co-investigator on experiments flown on the Voyager 1, 
Voyager 2, AMPTE, SAMPEX, WIND, Cassini, and IMAGE spacecraft and leads the 
CHEMS instrument team on Cassini.
