Biography

My primary research interests are complementary and integrative interventions for attention, mood, and anxiety issues in children and adults. Currently, I completed an international, multi-site study on supplementation with broad-spectrum micronutrients (vitamins+minerals) in children with ADHD, the Micronutrients for ADHD in Youth, (MADDY) Study. In addition to behavior changes, the SNACK Lab team is examining participants' biological samples in order to understand for whom and why the intervention confers benefit. We analyze participants' biological samples in order to identify biomarkers of treatment response. 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.
