Postdoctoral Research Associate



Sarie’s research mainly focuses on understanding the biological processes that shape social systems of non-human primates. She is particularly interested in understanding the selective advantage of group living and the interplay between intragroup cooperation and intergroup competition. To this end, she examines demographic, ecological, endocrine, and genetic factors mediating male and female social and reproductive strategies, individual strategies in cooperative group defense, intragroup coordination and decision making, and intergroup dynamics. She leads a long-term behavioral and ecological field research study on black howler monkeys (Alouatta pigra) in Palenque National Park in southern Mexico, and is also currently collaborating with Tony Di Fiore and his colleague Eduardo Fernandez-Duque (Yale University) in a comparative study of titi monkeys (Callicebus discolor) and sakis (Pithecia aequatorialis) to investigate the evolution and nature of monogamy.
