Dr. James Hinthorne has been a lecturer for the department of Physics and Geology since the Spring semester of 2008.  He is also a summer lecturer in Geology for Central Washington University.

Dr. Hinthorne graduated with his A.A. from Palomar College in San Marcos, California in 1962.  He went on to earn his B.A. in Geology and minor in Math from the University of California in Santa Barbara in 1965.  In 1967, he obtained his M.S. in Geology from the University of Massachusetts.   His thesis topic was "Geology of the Mt. Tom area, Massachusetts."  Dr. Hinthorne obtained his Ph.D. in Geology from the University of California, Santa Barbara, in 1974.   His dissertation is entitled "Origin of sanbornite and other barium silicate minerals." Prof. William S. Wise was his chairman.

From 1969 to 1980 Dr. Hinthorne was a Senior Scientist and Manager of the Methods and Applications Division for Applied Research Laboratories (ARL) based out of both Santa Barbara and Sunland, California.  While there, he developed instrumentation and software for commercial systems for electron microprobe, ion microprobe, X-ray fluorescence, and inductively coupled plasma optical spectrometry.  During his experience with ARL, Dr. Hinthorne would spend five years analyzing lunar samples and three years as research and applications department manager where he was responsible for about 20 researchers, engineers and programmers, and coordination with three corporate branches in Europe.

Dr. Hinthorne was a professor from 1980 to 2001, and Chair from 1980 to 1992 for the Department of Geology at Central Washington University in Ellensburg, WA.  During that time he taught courses in Physical Geology, Historical Geology, Mineralogy, Petrology, Geochemistry, Field Geology, Geographic Information Systems (GIS), Introduction to Computer Science, and FORTRAN.  In addition to working for CWU, he obtained research contracts for microanalysis of Columbia River Basalts, developed software for new GIS functions, and gave instrumental instruction at the Research Institute of the University of Petroleum and Minerals in Dharan, Saudi Arabia (1985).  Dr. Hinthorne retired from CWU in 2001.  Dr. Hinthorne went on to teach Geology during Summer Session 2007 at Central Washington University.
