Staff Profile

The Laboratory of Comparative Neuropsychology is now based at the University of Iowa, find more information here: https://medicine.uiowa.edu/neurosurgery/profile/christopher-petkov. I am still a Newcastle employee and work closely with Dr Yuki Kikuchi and Prof Tim Griffiths (please see their respective employee pages) and contact me with any questions.

The Newcastle lab webpage has been decomissioned, for the time being please see the University of Iowa webpage. We are working on a webpage that can better reflect the Newcastle-Iowa partnership that we are working on now funded by MRC, BBSRC, NSF and NIH BRAIN Initiative.
