Michael-Paul Schallmo, Ph.D.

Assistant Professor, Department of Psychiatry

Research Interests:

Dr. Schallmo began his research career in the lab of Dr. Scott A. Langenecker in the Neuropsychology Division at the University of Michigan. There he completed an honors thesis, using functional MRI to study word list learning as part of his B.S. in Brain, Behavior, and Cognitive Science. Dr. Schallmo then completed his Ph.D. in Neuroscience at the University of Minnesota, working in the lab of Dr. Cheryl A. Olman (Department of Psychology). His doctoral work used functional MRI and behavioral psychophysics to examine how early visual processing (e.g., contrast perception) is affected by psychosis. Next, Dr. Schallmo worked as a post-doctoral research associate in the lab of Dr. Scott O. Murray in the Department of Psychology at the University of Washington. This work examined how low-level vision (e.g., motion perception) is affected by autism spectrum disorder, using methods such as functional MRI, MR spectroscopy, and EEG. He joined the Psychiatry Department as an Assistant Professor in August 2017, as part of a team working on the Psychosis Human Connectome Project.
