Profile

Biography

• London Guildhall University
  BSc (1987)
  PhD (1990)

Graduated from the London Guildhall University in 1987, and stayed on to conduct research on the psychopharmacology of brain reward systems (PhD 1990). Moved to the University of Cambridge in 1990 to carry out postdoctoral research before arriving at York in 1994. Current research interests include the neural systems involved in learning and memory, brain reward systems and addiction. Teaches Psychopathology, and gives advanced course on the psychobiology of drug addiction.
