Program, and a Core Member of the Offord Centre for Child Studies.

Dr. Georgiades has a Ph.D. in Health Research Methodology from the Department of Clinical Epidemiology & Biostatistics, at McMaster University. Dr. Georgiades’ research examines issues related to the developmental trajectories as well as the clinical and biological heterogeneity in neurodevelopmental disorders, with a particular emphasis on autism spectrum disorder (ASD). Dr. Georgiades is a Co-Principal Investigator for the POND Network, an Ontario-wide research program that brings together a multidisciplinary team of scientists, clinicians, and community stakeholders who share the goal of improving the long-term outcomes for children with neurodevelopmental disorders (see Dr. Georgiades is also a Co-Investigator for a Canada-wide longitudinal study of children/youth with ASD (see
