Research

Tony J. Simon is the Associate Director of the IDDRC and Director of the IDDRC NeuroBehavioral Analysis Core. Dr. Simon research is focused on how neurocognitive, emotional and environmental factors interact to modulate learning difficulties and psychopathology in neurodevelopmental disorders, particularly chromosome 22q11.2 deletion syndrome (22q11.2/VCFS/DiGeorge syndrome), fragile X syndrome, and sex chromosome aneuploidies.  He also leads the 22q Healthy Minds Clinic that focuses on the mind, brain and behavior aspects of 22q11.2DS. Dr. Simon is interested in developing technology based interventions in the form of video games and internet based training that can enhance functioning, reduce symptom severity and improve quality of life. Current projects are focused on understanding the neurocognitive factors underlying learning difficulties in 22q11.2DS and related disorders and the also on understanding how cognition, emotion and environment interact to modulate stress, anxiety and psychiatric disorders in 22q11.2DS.
