Mikle South is Professor of Psychology and Neuroscience at Brigham Young University. He received a BA from Yale University followed by a PhD in Child Clinical Psychology at the University of Utah, working with Dr. Sally Ozonoff. He returned to Yale for postdoctoral training in developmental neuroimaging. His research program is focused on understanding the interaction of anxiety and autism in brain and behavior, and recent studies of sleep in autism and risk factors for suicidal thoughts and behaviors in young adults. He loves playing soccer and eating proper pizza.


  • PhD in Child Clinical Psychology from University of Utah, 2005
  • MS in Child Clinical Psychology from University of Utah, 2001
  • BA in Psychology from Yale University, 1994

Research Interests

My lab conducts research on emotion regulation and decision making, especially in autism. We study the shared brain mechanisms that underlie associated anxiety and autism symptoms. We use behavioral, psychophysiological (e.g., skin conductance, cardiac impedance), electroencephalography (EEG), and functional magnetic resonance imaging (fMRI) methods to measure response to various kinds of stress. I have active collaborations both on campus and internationally.
