Erik is an archaeologist, human evolutionary biologist and biometrician. His research revolves around the question: “What do people eat and why?” To answer it, he studies the evolution, ecology and diversity of behavior in prehistoric and modern foraging populations. Currently, he is interested in the effects that climatic change, variation of food-availability and-distribution had on the diet of the first North American foragers. As a biometrician and computational anthropologist he develops quantitative tools to answer questions in the context of the major dimensions of archaeological research: space, time and form. To this end he develops and implements optimal foraging models, 3D-morphometrics software, and statistical software for zooarchaeologists, spatio-temporal statistical models, and Geographic Information Systems (GIS).
