I worked as a post-doctoral associate with Dr. Sarah Brosnan from October 2010 until September 2011. During this time I studied responses to inequity in squirrel and owl monkeys as part of an NSF grant. In addition, I looked at the relationship between personality and responses to inequity in chimpanzees.

I received my Ph.D. in personality and social psychology from the University of Texas at Austin in 2010 working with Sam Gosling, Ph.D. My dissertation work focused on the development and validation of a chimpanzee personality rating scale using a variety of approaches and methods including behavior, endocrinology, physiology and injury and illness data. During graduate school I also worked on several personality projects with different species including humans and cheetahs that had health and well-being implications.

Following my time at GSU, I was a post-doctoral researcher position at the Lester E. Fisher Center for the Study and Conservation of Apes at the Lincoln Park Zoo. I was the project coordinator for Project ChimpCARE (http://www.chimpcare.org) in connection with and developed by Dr. Steve Ross. The main goal of the project was to improve the well-being of chimpanzees living in captivity in the United States, particularly those living as pets, performers and in other private housing. One main line of research was a multi-institutional study of ex-pet/ex-performer chimpanzees living in zoos and sanctuaries throughout the United States.  I am currently a postdoc at Disney's Animal Kingdom.
