Specialty: Peopling of the Americas, Paleolithic archaeology of Siberia, Beringia, and Western North America, lithic technology, geoarchaeology
Current Research Projects: Currently, I am directing and co-directing several field-based and lab-based projects in Siberia, Alaska, and the Great Basin, all focusing on initial human dispersals in these regions. In Siberia, I have analyzed several Upper Paleolithic artifact collections from pre-LGM and post-LGM contexts to explain Ice-Age hunter-gatherer land-use and am currently working with colleagues in Denmark and Russia to sample known Siberian Upper Paleolithic human remains for ancient DNA analyses, thereby supplementing our knowledge of human adaptations in Siberia before and after the LGM and searching for the Siberian origins of the first Americans. In Alaska, I have been directing excavations at the Nenana-Denali complex sites of Owl Ridge and Dry Creek in central Alaska. I have also been working with colleagues to search for other early Beringian sites in western Alaska and the upper Tanana river valley in eastern Alaska. From 2000-2009 I co-directed (with Ted Goebel and Bryan Hockett) excavations at Bonneville Estates Rockshelter, located in eastern Nevada. Currently, our team is focused on post-fieldwork analyses of the varied archaeological and paleoecological remains from the site. During summer 2012 I will be initiating a new project searching for first American sites in south-central and eastern Idaho.
