(1) studies of the patterns and components of familial aggregation of mental disorders and familial mechanisms for comorbidity of mental and medical disorders; (2) identification of early signs and risk factors for psychiatric disorders among high and low risk youth using prospective longitudinal high risk studies; and (3) large scale population based studies of mental disorders including high risk designs and prospective longitudinal research.

Dr. Merikangas is an author of more than 200 scientific publications and has presented lectures throughout the U.S. and in more than 20 countries. She is on the Editorial Board of several scientific journals and has been on the scientific advisory boards of numerous organizations and academic institutions including the John D. and Catherine T.

She recently chaired the Genetics Committee of the NIMH Strategic Plan for Mood Disorders. At NIMH, she is developing a program in genetic epidemiology integrated with statistical genetics and molecular biology to support research in the Mood and Anxiety Disorders Program.
