Xiaosi Gu, Ph.D.

Assistant Professor

Dr. Xiaosi Gu started her neuroimaging research at the Department of Psychology at Peking University (PKU), Beijing. After receiving a dual degree in Psychology and Economics from PKU, she moved to New York City to pursue a Ph.D. in Neuroscience at the Mount Sinai School of Medicine.  Dr. Gu then completed her postdoctoral training in computational psychiatry and decision neuroscience at the Wellcome Trust Centre for Neuroimaging at University College London (UCL), London, UK.  During her time in London, she also set up the world’s first computational psychiatry course at UCL. In 2015, Dr. Gu joined UT Dallas as an Assistant Professor at the School of Behavioral and Brain Sciences and Center for BrainHealth.

Dr. Gu's research in computational psychiatry examines the neural and computational mechanisms underlying human decision-making and social interaction in both health and disease, through a synthesis of functional magnetic resonance imaging (fMRI), brain connectivity modelling, neuropsychology (brain lesions studies), pharmacological challenges, and computational modelling. The goal of her research program is two-fold: 1) to help re-define and eventually improve human mental health; 2) to understand the neural and computational mechanisms of decision-making and social behavior. She uses a highly inter-disciplinary approach in her research, which involves the integration of theories and methods from cognitive neuroscience, behavioral economics, psychology, psychiatry, mathematics, biophysics, computer science, and more.
