Field Research
My fieldwork emphasizes hunter-gatherer populations of the Neotropics, and the behavioral ecology of small scale tribal peoples in Latin America. I have worked since 1977 with the Ache hunter-gatherers of Paraguay. In addition I carried out fieldwork with Hiwi hunter-gatherers of Venezuela, and the Mascho Piro, Matsiguenga and Yora populations of Manu Park Peru. I have visited dozens of indigenous communities throughout Latin America.
