Robert Maximilian Genta came to Dallas from the University of Geneva, Switzerland, where he was the Professor and Chair of the Division of Clinical Pathology for the past four years. Before that, he was the chief of the pathology department at the Veterans Affair Medical Center in Houston, Texas. He received his medical degree from the University of Turin, Italy, in 1971. After graduation, he studied linguistics in Copenhagen, Denmark, and then spent a year as a volunteer in Hodeida, Yemen, before deciding to become a pathologist and embark on his specialty training at Case Western University, Cleveland, Ohio.

He continued on to a fellowship in immunopathology at the University of Connecticut, followed by two years at the National Institutes of Allergy and Infectious Diseases, NIH, Bethesda, Maryland. He has held faculty positions at the University of Cincinnati, Ohio, the University of Washington, Seattle, and Baylor College of Medicine in Houston, Texas.

Dr. Genta is a member of the editorial board of several specialty journals, including Human Pathology, Helicobacter, and Gastric Cancer, and of the advisory board of Nature Clinical Practice - Gastroenterology and Hepatology and the American Journal of Gastroenterology. He is an active member of numerous professional societies, including the US International Academy of Pathologists (USCAP) and the European Society of Pathology, and he is a Fellow of the American College of Gastroenterology. He is the author of more than 200 scientific articles, 40 book chapters, and the editor of two books.

Dr. Genta’s research interests are focused on gastrointestinal infections, gastritis, Helicobacter pylori, gastric cancer and reflux-related conditions. He is also interested in the epistemology of the diagnostic process in histopathology and has lectured widely throughout the world on these areas.

A compulsive linguist, he speaks seven languages fluently (albeit all with an accent) and can converse in five or six more. Robert is married to Marcia, a rheumatologist; they have two sons, Maximilian (born in 1988) and Benjamin (1995).
