Research Interests

Dr. Barrett joined the Division of Gastroenterology at the University of California, San Diego in 1985 and rose to her current rank of Professor of Medicine in 1996. September 2006, Dr. Barrett was appointed Dean of Graduate Studies.

Dr. Barrett's research interests center on the normal and abnormal biology of the intestinal epithelium and their relevance to a variety of digestive diseases including inflammatory bowel diseases, infectious diarrheal diseases, and peptic ulcer disease.

She has received a number of honors for her research, including the Bowditch and Davenport Lectureships of the American Physiological Society, and being awarded the degree of Doctor of Medical Sciences, honoris causa, by Queen University Belfast.

She has been highly active in professional societies and in scholarly editing. She is also the author or editor of several books and monographs and almost two hundred peer-reviewed journal articles, book chapters, and reviews.

Most recently, in 2006, she was appointed as Dean of Graduate Studies at UCSD. In this capacity, she serves as a member of the senior academic management team of the Institution and oversees the recruitment, academic advancement and climate for more than 4,000 masters and doctoral students.
