Robert Torrence

Title:Adjunct Faculty
Office:Warde Academic Center


Dr. Robert Torrence earned his Ph.D. in Psychology, with a focus on Cognitive Neuroscience, from Colorado State University in 2018. He obtained his M.S. from Northern Michigan University in 2015 and a B.A. from the University of Illinois at Springfield in 2013. He received additional research training as a postdoctoral research fellow in the Department of Pharmacy Practice at Wayne State University. He joined the Psychology Division at SXU in 2019.

Dr. Torrence's research focuses on how recreational cannabis use effects emotional processing (e.g. attentional bias and awareness of emotional facial expressions and images). He has a background in using near-infrared spectroscopy (NIRS), electroencephalography (EEG), magnetic resonance imaging (MRI), and functional MRI (fMRI). Dr. Torrence also has an interest in studying emotional processing in anxiety (including PTSD) and depression related disorders.
