Professor Emeritus |Archaeology

Special Interests

Geoarchaeology, North American Southwest, lithic technology and analytical chemistry in archaeology, hunter-gatherers.


My research for the last 30 years has focused on aspects of geoarchaeological science in concert 
with lithic technology mainly in the North American Southwest.  I directed the National Science 
Foundation sponsored Geoarchaeological XRF Laboratory at Berkeley training many 
undergraduate and graduate students in the application of x-ray fluorescence spectrometry in 
archaeology, and field practice in archaeological petrology until retirement in 2011.  I continue 
the Geoarchaeological XRF Laboratory in New Mexico serving many of those same students 
who have gone on to careers in academia, government, and the private sector.  In 2011 the 
Society of American Archaeology bestowed the Award for Excellence in Archaeological 
 "For his integrative approaches in analytical, scientific, and technological lithic 
studies, including their applications to social organization of procurement, trade, 
and exchange, and his broad-ranging contributions to scholarship in the New and 
Old World"
My research focus is still the North American Southwest, but continue collaborations with 
colleagues in Mexico, Europe and Africa, including work in Neanderthal contexts in the Russian 
Caucasus, and early hominid sites in Ethiopia with my former colleague Tim White at Berkeley 
and his students and post-doctoral researchers.


After serving eight years in the U.S. Marines as an ordnance maintenance officer, I received my
A.B. in Anthropology and Geological Science at San Diego State University, my M.A. in 
Anthropology at SDSU, and my Ph.D. in Anthropology at Arizona State University.  I came to 
Berkeley in 1990 at first in the Lowie Museum, now the Phoebe Hearst Museum of 
Anthropology, and later as faculty in the Department of Anthropology
