Gregory S. Young, Ph.D.Co-Investigator

An assistant research scientist in the Department of Psychiatry and Behavioral Sciences, Dr. Gregory Young is a developmental psychologist. He specializes in longitudinal research design and analysis, with an interest in eye-tracking and behavioral coding as ways to measure intra-individual change as it relates to typical development and the early onset of developmental disorders such as autism. He collaborates with Drs. Sally Rogers and Sally Ozonoff on studies of the onset and treatment of autism in infant siblings and young preschoolers, and with Dr. Julie Schweitzer on the role of norepinephrine and the locus ceruleus in ADHD as measured by pupil dilation dynamics. Dr. Young also has specific interests and expertise in statistical analysis techniques using hierarchical generalized models as applied to growth curve analysis, Rasch measurement modeling, and sequential analysis of time series data.  Additionally, he has expertise in database programming and advanced data processing algorithms for use with methodologies such as eye-tracking and behavioral coding.  Dr. Young reviews regularly for a number of publications including Journal of Child Psychology and Psychiatry, Autism Research, Biological Psychiatry, and Biological Letters.
