Katey is a third-year graduate student in the clinical psychology program working with Dr. Lauren Ellman. She graduated from the University of Missouri- Columbia with a BA in Psychology in 2017 and worked as a post-baccalaureate research assistant for the Human Connectome Project at Washington University in St. Louis. Katey is interested in using multi-modal neuroimaging techniques to assess correlates of psychosis-risk as well as schizophrenia-spectrum disorders.
