I obtained my doctoral degree from University of Manchester Medical School in 2014, studying social and value-based decision-making impairments in patients with major depressive disorder and their neurobiology. After my graduation, I have worked as a postdoctoral researcher in RIKEN Brain Sciences Institute (Tokyo) and Center for Information and Neural Networks (CiNet; Osaka) working on computational models of decision-making under uncertainty and in competitive, social interactive games.
I am interested in investigating models of reinforcement learning and social interactive decision-making in patients with depression and healthy volunteers undergoing pharmacological manipulation.

My other interests involve evolutionary models of human social behaviours.
