My fieldwork is currently concentrated within the modern Greater Yellowstone Ecosystem.  In August 2002, I conducted a two week trip focused on collecting samples for an isotopic study aimed at determining whether or not resource partitioning in mammals can be determined using stable carbon isotopes within a dominantly C₃ ecosystem.  The fieldwork itself consisted of following large ungulates around to collect "fresh" fecal samples.  During the trip I managed to collect samples from five of the seven large ungulate genera.  Samples were obtained from Antilocapra, Bison, Cervus, Odocoileus, and Ovis, while Alces and Oreamnos were not gathered.  I am planning on conducting another trip in Summer 2003 to supplement the current sampling.

In September 2002, I  participated in a field season to the Virgin Valley/ Thousand Creek Miocene fossil localities in Northern Nevada.  This trip, directed by Edward Davis (UC Berkeley), focused on fossil and radiometric dating sample collection as well as the re-identification and correlation of localities that had been identified in the early-1900's by Annie Alexander and W. D. Matthew.

I  also participated in the Geoecology along the Yellowstone Hotspot (Summer 2000) field course directed by Anthony Barnosky (UC Berkeley).  This four week field course followed the track of the Yellowstone hotspot from the early Miocene of Oregon to its present position in Wyoming.  Along the trip, we collected at John Day, OR; the Beatty's Butte area of southwest OR; Hagermann Fossil Beds, ID; Railroad Canyon, Idaho/MT; Hepburn's Mesa, MT; propecting Holocene deposits of Yellowstone National Park.
