Joel Kleinman, M.D., Ph.D. is the Associate Director, Clinical Sciences and the Co-Director of the Molecular Neuropathology Section at the Lieber Institute for Brain Development (LIBD), Johns Hopkins University in Baltimore, MD. He is a Professor in the Department of Psychiatry & Behavioral Sciences at the Johns Hopkins University School of Medicine. Dr. Kleinman is also on the board of directors for the Sheppard-Pratt Lieber Research Institute, a clinical research center focused on understanding the biology of schizophrenia, autism, and other developmental neuropsychiatric disorders.
Dr. Kleinman received his B.S. in Biochemistry in 1966, his M.D. in 1973, and his Ph.D. in Pharmacology in 1974 from the University of Chicago. He interned at San Francisco General Hospital (University of California Medical School in San Francisco) and completed a residency in psychiatry at Massachusetts Mental Health Center (Harvard Medical School) as well as a residency in Neurology at the George Washington University School of Medicine.
Over the last 41 years at the NIMH and LIBD he has helped to amass what is widely regarded as one of the best collections of postmortem human brains for the study of the molecular biology of brain development and related disorders, especially schizophrenia. He has been both a pioneer and leader in this area of research with over 350 peer-reviewed papers. Recently, his research has focused on allelic variation, alternative transcripts and epigenetic modifications in human brain development, schizophrenia and a number of other psychiatric disorders including bipolar disorder, depression and PTSD.
