Professor of Medicine 
Phone: 205-934-4769


Dr. Schroeder earned his B.S. in chemistry from Texas A&M University and both his Ph.D. in cell biology and M.D. from Baylor College of Medicine.  After residency in internal medicine at the University of Kentucky, he completed a fellowship in medical genetics and a post-doctoral fellowship in immunology at the University of Washington and Howard Hughes Medical Institute (Seattle).  In 1988, he joined the UAB faculty as an Assistant Professor of Medicine, rising to Professor in 1998.  Dr. Schroeder has received an RJR Nabisco Research Scholar in Immunology in 1988 and was a Fogarty International Scholar (1995-1996) at the Institute for Genetics, University of Cologne, where he did his sabbatical.  He has been both member and chair of NIH Study Sections and has served as Associate and Section Editor for The Journal of Immunology.  He is the Director of the UAB Program in Immunology and the Immunology Training Grant.  He holds joint appointments in Microbiology and Genetics

Dr. Schroeder’s laboratory has a long-standing interest in the development of the human antibody repertoire.  Among his many scientific contributions are mapping the linkage of human VH, DH and JH region gene segments and characterization of the CDR-H3 repertoire in early B cell progenitors.  An important research focus also has been the role of immunoglobulin CDR-H3 in auto-immune diseases.  Recently, he began to investigate the binding and neutralization properties of immunoglobulin CDR-H3 for HIV-1.

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.
