Claudia conducted her PhD investigating social modulation of heart rate in greylag geese at the Konrad-Lorenz research station in Austria. After her PhD she broadened her expertise in the field of social cognition, investigating cognitive mechanisms underlying cooperation in carrion crows and ravens.
She has held several post-doctoral periods in international labs (CNRS Strasbourg, NTNU Trondheim, Max Planck Institute for Ornithology Seewiesen, University of Valladolid).
Claudia is chair of our Animal and Environmental Biology Group’s Research Ethics Committee and a member of the Faculty of Science and Technology’s Research Ethics Committee.
She is also Deputy Director of our Animal and Environment Research Group.
Claudia is Deputy Director of our Animal and Environment Research Group.
Claudia welcomes enquiries from prospective research students in the areas of her research interests.
