Anthony Difiore, Ph.D.
University of Texas, Austin

Tony and I met while we were both graduate students at UC Davis. For many years, we dreamed about joining efforts to do research and training in anthropology and primatology in Latin America. In 2002, we initiated a long-term research program to understand the socioecology of monogamy, pairbonds and parental care in New World primates. We now study together titis, sakis and owl monkeys in Tony’ primary field site in the Amazon rainforests of Yasuní National Park, Ecuador and in the Owl Monkey Project’s site in the Chaco.

Claudia Valeggia, Ph.D.
University of Pennsylvania

My colleague and spouse, Claudia and I have run parallel research paths since we met at the University of Buenos Aires where we studied together memory and learning in crabs.  Since then we have always collaborated on numerous projects. Together, we founded the Fundacion ECO in 1999, with the aim to promote education in Argentina. At her field site in Formosa, Claudia conducts Reproductive Biology research with the Toba and Wichí of the Argentine Chaco. Her knowledge about hormones, behavior, and life-history and her Reproductive Ecology Laboratory at Penn  have been instrumental in the success of my research endeavors.
