My interests center around long-term human ecology and landscape dynamics with ongoing projects in the Mediterranean (late Pleistocene through mid-Holocene) and American Southwest (Holocene-Archaic). I've done fieldwork in Spain, Bosnia, and various locales in North America and have expertise in hunter/gatherer and early farming societies, geoarchaeology, lithic technology, and evolutionary theory, with an emphasis on human/environmental interaction, landscape dynamics, and techno-economic change.

Quantitative methods for characterizing socioecological dynamics are increasingly critical to archaeological research and are an important focus of my research, especially emphasizing spatial technologies (including GIS and remote sensing), modeling and simulation, exploratory data analysis, and morphological analysis.
