Carol A. Tamminga, MD

Site PI for UT Southwestern; Lead PI for BSNIP2

Carol’s career has focused on the examination of psychiatric brain diseases with an emphasis on psychotic disorders using patient volunteers and postmortem brain tissue with a goal to understand the cellular and molecular mechanisms of psychotic illness, which remain even now undiscovered.

Dr. Tamminga’s research has been directed to identifying cellular and molecular mediators of psychosis in schizophrenia, to achieve an understanding of the basic biology of the dimension and to develop novel treatments.

Carol is responsible for the overall performance of the Dallas site in carrying out the BSNIP2 research project.
