Tammie L.S. Benzinger, MD, PhD, is a professor of radiology and serves as chief of MRI service at Mallinckrodt Institute of Radiology (MIR) at Washington University School of Medicine in St. Louis. Benzinger’s research group, part of MIR’s Neuroimaging Lab, primarily focuses on the study of Alzheimer’s disease, mild cognitive impairment, autosomal dominant Alzheimer’s disease (ADAD) and related disorders. She uses PET and MRI imaging to investigate biomarkers she believes will become significant tools in detecting and diagnosing degenerative brain diseases before symptoms occur. Her group also serves as the imaging core for the Knight Alzheimer’s Disease Research Center, international studies of ADAD, the Dominantly Inherited Alzheimer Network (DIAN) and the DIAN-Therapeutic Unit.

In 2018, Benzinger, who is also a professor of neurological surgery, received the Women in Neuroradiology Leadership Award from the American Society of Neuroradiology and the Distinguished Investigator Award from the Academy for Radiology and Biomedical Imaging Research. She is an alumna, having completed both her diagnostic residency and a fellowship in neuroradiology at MIR. Benzinger earned both her medical and doctoral degrees from the University of Chicago and her bachelor’s degree from Williams College in Williamstown, Massachusetts.
