Patricia Cowell is a Professor of Cognitive Neuroscience at the University of Sheffield. Before coming to Sheffield she was a Postdoctoral Research Fellow (1992-1995) in the Brain Behavior Laboratory, University of Pennsylvania Medical School with a research focus on cortical sex differences in adults in relation to aging and schizophrenia. Patricia completed her PhD (1992) and masters (1990) in Biobehavioral Sciences at the University of Connecticut through research on the corpus callosum and behavioural laterality in humans and rodents. Her undergraduate education at Boston University (1983-1987) was in Psychology and Statistics.
