Barbara Cornblatt, PhD, MBA, is a professor of psychiatry and molecular medicine at the Donald and Barbara Zucker School of Medicine at Hofstra/Northwell. For more than 40 years, she has focused her research on the causes and treatment of serious mental illness. 

Dr. Cornblatt directs the Recognition and Prevention (RAP) program, which she founded in 1998 at the Zucker Hillside Hospital. RAP is dedicated to treating early warning signs of mental illness in adolescents and young adults, and is one of the longest running centers of its kind in North America. More than 800 young people have participated in both the research and treatment components of this program. Early treatment in the RAP Clinic has been consistently associated with a high rate of clinical improvement. 

Dr. Cornblatt has authored and co-authored over 250 scientific articles, and has given many scientific talks nationally and internationally to a variety of prestigious scientific organizations, hospitals and consumer groups. She spearheaded several of the early collaborations that launched the psychosis high risk field, including being the founder and co-director of the International Prodromal Research Network, which initially sponsored international prevention studies. She was also a founding member of the North American Prodrome Longitudinal Study (NAPLS) 9-site consortium, one of the first large prevention collaborations worldwide.
