Research Summary
I am an imaging scientist and breast cancer researcher with broad experience in the area of biomedical research. Work in my laboratory focuses on the development of MRI techniques for breast cancer diagnosis and treatment response assessment. My laboratory works closely with a multi-disciplinary team of radiologists, surgeons, oncologists, basic science researchers and advocates to optimize MRI methods for the clinical management of breast cancer patients. The overall goal of our interdisciplinary research program is to develop imaging-based biomarkers that can be used in combination with clinical and molecular information to individualize treatment strategies.
I lead as Principal Investigator, the multi-center ACRIN trials 6657 and 6698, evaluating dynamic contrast-enhanced (DCE) and diffusion-weighted (DW) MRI respectively, for assessing treatment response as part of the ISPY-1 and ISPY-2 neoadjuvant breast cancer trials. Under an NCI Academic-Industrial Partnership (AIP) grant with commercial partner Hologic, Inc., (R01 CA132870), my laboratory developed and deployed a software platform for real-time measurement of breast tumor response using DCE-MRI, for use in clinical trials. The Hologic software received FDA IDE approval in 2010 and is now incorporated in the response-adaptive patient randomization engine of ISPY-2. Under prior funding from the NCI Quantitative Imaging Network (QIN) (U01 CA151235), my laboratory led efforts to improve the integration of quantitative imaging (QI) in breast cancer clinical trials through the development of standards and quality control processes and improved diffusion-weighted MRI approaches for tumor response measurement.
As an applied scientist involved in the early development of breast MRI, I believe I bring a unique perspective and appreciation of the factors that drive and shape the development of new breast imaging technologies. I have served on and chaired numerous grant review panels in both the areas of medical imaging and breast cancer research.
I am an active educator and faculty member at UCSF and in the UCSF/UC Berkeley Bioengineering Graduate Program and I teach formally in the UCSF Master’s in Biomedical Imaging degree program. I have been involved in the training and research supervision of graduate students, post-doctoral fellows and junior faculty for over 20 years.
