W. Thomas London, MD: "Why is Hepatitis B important?"

Dr. W. Thomas London was a keynote speaker at the B Informed Educational Forum Program held in New York on September 23, 2004. For more than three decades, W. Thomas London M.D. has been a national leader in the effort to unleash the secrets of the hepatitis B virus, which has infected one in 20 Americans and chronically infects 1.25 million. Dr. London specializes in researching how hepatitis B impacts the liver, and how this viral infection promotes liver cancer. Over the course of his varied professional life, he has written about hepatitis B from the perspective of an epidemiologist, a clinician and a virologist.

Dr. London is a senior member, focusing on viral hepatitis in the Division of Population Science at the Fox Chase Cancer Center in Philadelphia. This division identifies groups of people with high cancer risks, such as those with hepatitis B, to develop community-based strategies to help people reduce their cancer risks and detect cancer early. The division also studies how environmental agents and genetic factors interact to predispose people to cancer.

Until recently, Dr. London was also an adjunct professor of epidemiology at the Center for Clinical Epidemiology and Biostatistics at the University of Pennsylvania School of Medicine and associate editor of Cancer Epidemiology Biomarkers and Prevention. He is widely published in peer-reviewed publications.

Dr. London received the Distinguished Scientist Award in 1998 from the Hepatitis B Foundation in Doylestown, PA, and the Distinguished Interdisciplinary Research Award in 1999 from the American Cancer Society, Southeast Region. He sits on the Board of Directors of the Hepatitis B Foundation and is a member of the National Institutes of Health Reviewers Reserve.
