Professional Interests

Dr. Barry's current research focuses on the chemoprevention of cancer and the pharmacogenetics of chemopreventative agents. She is especially interested in the role and mechanism of action of anti-inflammatory drugs (such as aspirin) and nutritional supplements (such as calcium, vitamin D and folate) as chemopreventative agents for cancer. Using data from clinical trials, Dr. Barry is currently investigating how genetic polymorphisms may modify the effectiveness of some of these drugs in the prevention of colorectal adenomas. In addition to her interest in cancer, Dr. Barry has a long-standing interest in calcium and vitamin D regulation and their role in bone health and disease (osteoporosis).
