Chris Jazwa is a post-doc alumnus of the HEnDy lab at Penn State, now Asst Professor of Anthropology at U. Nevada Reno where he is working on landscape modification in the Western Desert of Australia and human environmental interactions in prehistoric coastal California. His research is a new component of our team's ongoing NSF sponsored project on resource use and landscape ecology among Martu. The new project involves using stable isotopic measurements from collagen of kangaroo bones from the archaeological record to reconstruct macropod diet and potential landscape level changes in anthropogenic habitat modification in the past. Dr. Jazwa completed his PhD in Anthropology at Penn State with his thesis focused on the archaeology of human-environmental interaction in California's Channel Islands. He has published widely on his archaeological and ecological work.
