Professor of Medicine, Radiology and Pathology
Phone: 205-975-6414



Dr. Zinn earned his B.A. in Chemistry from the University of Missouri.  Remaining at the University of Missouri, he went on to earn a Masters in Chemistry and a D.V.M, followed by a Ph.D. in Biochemistry.  In 1995, he relocated to UAB, rising to Professor in the Departments of Medicine, Radiology and Pathology in 2003.  Dr. Zinn has received numerous awards for his scientific accomplishments, including the Benadict Cassen Imaging Award (twice) and the Southern Societies Young Faculty Award.  He holds an array of patents pertaining to the generation of diagnostic radioisotopes.

Dr. Zinn’s research focus is the development of novel imaging techniques for the screening and precise location of tumors and metastases.  He also has lead efforts to develop reporter systems for the imaging of gene transfer and apoptosis in vivo.  In addition, his laboratory has pioneered non-invasive small animal imaging for the study of biological, infectious and immunological events in vivo.

Preventing, diagnosing, and caring for patients with digestive and liver-related conditions

The University of Alabama at Birmingham Division of Gastroenterology and Hepatology is spearheading the crusade to treat digestive and liver-related disease by promoting clinical education and research in all areas of the specialty. We enhance patient experiences by providing compassionate, competent, professional clinical care through expert physicians, well versed in treating severe and complex gastrointestinal and liver disorders.


Faculty, fellows and staff actively participate in developing new therapies associated with gastrointestinal disorders through comprehensive research facilities and programs within UAB.


The division’s fellowship programs deliver advanced training, superior knowledge and enhanced skills for gastroenterologists and hepatologists of the future.

Patient Care

GI & Hepatology sets the standard of patient care by developing compassionate, patient-centered, and clinically advanced physicians and staff.
