Personal History:

Dr. Carpenter's major professional interest is severe mental illness, especially schizophrenia. His approach to the care and study of patients is within the context of a broad medical model integrating biological, psychological and social data as they pertain to diagnosis, treatment and etiology. He has made original and fundamental contributions in psychopathology, assessment methodology, testing of new treatments, research ethics, and translational science. He has authored over 400 clinical and scientific articles, book chapters and books.
Dr. Carpenter is Editor-in-Chief of Schizophrenia Bulletin, a journal with 2011 impact factor rating of 8.8 ranking it fourth out of 129 journals in the field.  He also serves on a number of editorial boards including the Archives of General Psychiatry.

Special professional assignments include service on the NIMH Intramural Research Program Board of Scientific Counselors and as a consultant and reviewer for NIMH and NIH on many topics. He chaired the NIMH Research Scientist Career Development Committee and the NIMH National Plan Committee on Treatment Research. Dr. Carpenter has been principle investigator on five types of NIMH Center grants and is currently focused on integrating an animal model, a human phenotype model, and a clinical trials model in developing novel treatments for cognition and negative symptoms of schizophrenia.

He provided expert testimony in the cases of the U.S. Government versus John Hinckley and the Commonwealth of Pennsylvania versus John DuPont and in 1989 was a member of the State Department delegation to inspect the political use of psychiatry in the Soviet Union. He is a recipient of major national and international research awards and was elected to the Institute of Medicine of the National Academy of Sciences in 1998.
