Professor and Head of the Pennsylvania State University Department of Biochemistry and Molecular Biology Scott B. Selleck MD, PhD visited our Grand Rapids and East Lansing campuses last week, delivering a different presentation at each location. Dr. Selleck studies the molecular mechanisms of nervous system development, with particular emphasis on proteoglycans as signal pathway regulators, and the genetics of Autism Spectrum Disorder. Recordings of Dr. Selleck's two presentations are available below.
