Caitlin O’Connell


Caitlin O’Connell graduated from Loyola College in Maryland with a B.S. in biology.  She got her start in primatology working as a field assistant on the Lomas Barbudal Monkey Project, studying wild white-faced capuchin monkeys in Costa Rica.  Caitlin then joined the lab of Dr. Cheryl Knott as a Ph.D. student here at BU and began studying wild Bornean orangutans.  Caitlin is broadly interested in primate behavior and physiology. She is currently examining the sociality of orangutans – how it is influenced by fruit availability, demographics, and life history. She is also investigating the interplay among social behavior, stress and parasites to better understand the costs of being social.
