My primary research interests are complementary and integrative interventions for attention, mood, and anxiety issues in children and adults. Currently, I am running a study on supplementation with multivitamin/minerals in children with ADHD, called the Micronutrients in ADHD Youth, The "MADDY" Study. I have conducted research on mindfulness strategies to reduce stress and improve mood in adolescents, and have looked at childhood factors that impact response to depression treatment in adults.
