About Diana Armstrong:

Diana has been with the Davee Center for Epidemiology and Endocrinology since 2007, initially as the research assistant before being promoted to endocrinology laboratory associate in 2008. The majority of her time is spent running the day-to-day operations of the endocrinology lab. She is also responsible for training and overseeing the graduate and undergraduate students in the lab.

Diana has a special interest in marmoset and tamarin physiology and behavior. She has done research on pied tamarins and black tufted-ear marmosets. Currently she’s investigating factors that could increase reproductive success in pied tamarins and lead to better understanding of their physiology and behavior.

Prior to working at Lincoln Park Zoo, Diana completed a keeper internship at Brookfield Zoo Tropic World, was an animal keeper at Willowbrook Wildlife Center and a research assistant at University of Nebraska at Omaha, and volunteered as a docent at the Henry Doorly Zoo in Omaha.
