Research Summary

I am the Director of the University of California, San Francisco (UCSF) Helen Diller Family Comprehensive Cancer Center (HDFCCC), a multidisciplinary research and clinical care organization that is one of the largest cancer centers in the Western United States. I also serve as Senior Vice President for Cancer Services, UCSF Health.

Following my education and postdoctoral fellowships, in 1999, I was appointed the first Director of the Breakthrough Breast Cancer Research Centre at the Institute of Cancer Research (ICR). The Centre is now recognized as one of the leading Breast Cancer Centre’s internationally and has more than 120 scientists and researchers working on aspects of the disease ranging from basic molecular and cellular biology through to translational research and clinical trials. My directorship ended in January 2011 when I was appointed Chief Executive of the ICR. I undertook this role until July 2014, at which time I was named incoming Director of the HDFCCC.

I was a key part of the team that in 1995 discovered the gene BRCA2, which is linked to an increased risk of some types of cancers. Ten years later, I identified a way to exploit genetic weaknesses in cancer cells including mutated BRCA2, leading to a new approach to cancer treatment. This approach is now being tested in numerous clinical trials.

My current research reflects my passion for the development of personalized cancer medicine, translating laboratory studies into improvements in patient care. I am also joint leader, with Professor Tony Swerdlow, of one of the world’s most comprehensive and largest (>100,000 participants), studies of breast cancer causation, the Breakthrough Generations Study (
