Dr. Stolz’s major areas of research interest are mechanisms of protein mediated intracellular transport of bile acids in the liver, molecular characterization of Aldo-Keto Reductase supergene family members in rat, mouse and human, dysregulation of hormone catabolism in human breast and prostate cancers, and drug-induced liver injury, among others.

Dr. Stolz earned his medical degree at Albert Einstein College of Medicine. He then performed his residency at Mt. Sinai Hospital, immediately followed by a Gastroenterology Fellowship at UCLA. Dr. Stolz has been a part of the Division of Gastrointestinal and Liver Diseases since 1990, earning tenure shortly after.
