San Francisco, CA
Summary of Qualifications
I am a scientific director with more than 20 years of experience in biotechnology industry. Throughout my career I have worked with innovative technologies to identify genes that make effective targets for specific molecularly-targeted therapies and helped to drive these therapies into the clinic. Recently, I have championed the use of genomic and molecular characterization to better match animal models with the right patient populations to increase the effectiveness of molecularly targeted therapies. I have played a major role in starting a new company and have a passion for evaluating novel technologies that may lead to more efficient drug discovery platforms.
