Dr Lydia M. Hopper

I am the Assistant Director of the Lester E Fisher Center for the Study & Conservation of Apes, Lincoln Park Zoo, Chicago, USA. It is my role to help with the design, coordination, and running of our in-house behavioral and cognitive research with our chimpanzees, gorillas and Japanese macaques. I am also Chair of Lincoln Park Zoo's Institutional Review Board. In addition to my role at the Zoo, I am an adjunct Assistant Professor at Northwestern University, USA, and an Honourary Research Fellow at the University of Birmingham, UK.
