On August 4-7, State College will host the 18th National Autism Conference. Today on Take Note we talk with Dr. Daniel Notterman about the current state of autism research. Dr. Notterman has just stepped down from the position of vice dean for research and graduate studies -- and professor of pediatrics and biochemistry -- at Penn State College of Medicine. He’s going to Princeton University, where he’ll continue his research into the causes of autism. WPSU’s Emily Reddy talked with Dr. Notterman about where we are in our understanding of autism.
