Fiona Molloy, Ph.D.

T-32 Post-Doctoral Fellow, U-M Addiction Center


M. Fiona Molloy, Ph.D. is a Postdoctoral Research Fellow at the University of Michigan Addiction Center in the Department of Psychiatry. Her research focuses on understanding the links between neural connectivity, brain activity, and behavior, and using computational modeling to predict how these components contribute to individual and clinical differences in humans. She is also interested in developing mathematical models and machine learning methodology to improve estimation of individual differences in decision-making, neural activation, and neural network topography.
