I have 20 years of experience, and specialize in the field of psychiatry with specific knowledge in the areas of child and adolescent psychiatry, pediatric psychopharmacology and obesity and psychiatric medications. I have published on such topics as pediatric psychopharmacology, obesity and psychiatric medications and pediatric aggression. I have testified 50 times on topics such as mental health commitment of mentally ill adolescents, pediatric psychopharmacology and antipsychotic medication use in child and adolescent psychiatri. I co-authored a textbook of pediatric psychopharmacology most widely used by child psychiatry and pediatric training programs and recently co-authored a study demonstrating the protective effects of Vitamin D treatment on preventing weight gain in adolescents taking antipsychotic medication.
