Dr. Munster is a physician scientist who received her medical degree from the University of Bern, Switzerland. She completed her Internal Medicine training at Indiana University Medical Center and Heme-Onc Fellowship at Memorial Sloan-Kettering Cancer Center, New York where she then served on faculty as a breast cancer specialist. She subsequently joined the Division of Breast Oncology and Experimental Therapeutics Program at Moffitt Cancer Center in Tampa, Florida, as the Scientific Director of Breast Research and Co-Chair of the Experimental Therapeutics Program prior to moving to the University of California, San Francisco. Dr. Munster is the Marian Moghadam Safinia Distinguished Professor in Residence, the Program Leader for Molecular Oncology, and the Co-Leader of the BRCA Center for Research and Hereditary Cancer Clinic at the Helen Diller Family Comprehensive Cancer Center.
Dr Munster is also the founder and current CEO of Alessa Therapeutics, a UCSF spin-off, developing organ selective localized therapeutic interventions. She serves on several NCI study sections including on the steering committee for PREVENT. Additionally, she is the Co-chair of the Experiential Therapeutics committee at the Alliance of Clinical Trials in Oncology, chairs the Exam Committee for the American Board of Internal Medicine (ABIM), and advises AnCan, a large national patient advocacy program as a board member.
Her NCI funded basic research laboratory is focused on epigenetic and inherited factors of tumor development and treatment. Dr. Munster’s clinical mission is to translate novel scientific discovery more rapidly to patient care by integrating multi-modality novel treatment strategies and new detection methods with the goal to allow patients with incurable cancer real time and broad access to scientific advances.
Dr. Munster has published in numerous peer-reviewed scientific journals and textbooks. She has authored “Twisting Fate”, a book on her journey of carrying the BRCA mutation.
Michael Varney, PhD
Dr. Mike Varney is a pioneer drug discoverer and biotech leader. As one of the original fifteen employees at Agouron, a biotech based in San Diego, he built a team that developed protein-structure based design, a novel approach to drug discovery that is utilized globally by drug discovery teams today. In 1997, the Agouron team launched Viracept, an HIV protease inhibitor that achieved the highest first year launch sales of any biotech product at the time. Dr. Varney’s leadership at Agouron resulted in the discovery of a number of currently marketed anti-cancer agents including Xalkori and Inlyta, a drug that won the American Chemical Society’s Heroes of Chemistry Award in 2018.
In 2005, Dr Varney was recruited to Genentech, the US based R&D organization in Roche, to expand the organization’s drug discovery capabilities to include small molecules. Focused on agility and pioneering science, Varney built a team-based organization that today produces more that 40% of Genentech’s development portfolio including the marketed anticancer agents Erivedge and Cotellic
In 2015, Dr Varney was appointed Executive Vice President and Head of Genentech’s Research and Early Development (gRED) and a member of the Roche Corporate Executive Committee in Basel. In this role, he was responsible for all aspects of gRED innovation, drug discovery and development. Varney also focused on building a team-based culture empowered to clear the pathto patients. Under his leadership, gRED teams discovered and developed successful medicines that include Venclexta with AbbVie, the first bcl‑2 inhibitor and Polivy, an antibody drug conjugate for the treatment of DLBCL. Pioneering molecules in the clinic include Mosunetuzumab, a bispecific antibody targeting CD20, and GDC-9545, a next generation estrogen receptor degrader. Dr. Varney retired from Genentech in July 2020, leaving a diversity of drug platform types that includes personalized therapeutic vaccines and cellular therapies.
Currently, Dr. Varney is an advisor, Board member and SAB member for ERASCA and Numerion and an SAB member for a number private and public biotechnology companies.
