Carolyn Bertozzi grew up in a science family with a physicist father. But it was organic chemistry that “clicked” for Carolyn and started her down the path of understanding biology at a molecular level. Daniel Chen and Carolyn Bertozzi discuss her work in glycobiology. Bertozzi’s research finds that glycosylation has consequences in immune modulation, and that glycobiology plays an important role in human disease that has historically been underexploited in drug development. Finally, Chen and Bertozzi talk about gender representation in science and the importance of female role models for both women and men.

BIO(s) 

Carolyn Bertozzi, PhD, Professor, Chemistry, Stanford University
Carolyn Bertozzi is the Baker Family Director of Stanford ChEM-H and the Anne T. and Robert M. Bass Professor of Humanities and Sciences in the Department of Chemistry at Stanford University. She is also an Investigator of the Howard Hughes Medical Institute. Her research focuses on profiling changes in cell surface glycosylation associated with cancer, inflammation and infection, and exploiting this information for development of diagnostic and therapeutic approaches, most recently in the area of immuno-oncology. She is an elected member of the National Academy of Medicine, the National Academy of Sciences, and the American Academy of Arts and Sciences. She also has been awarded the Lemelson-MIT Prize, a MacArthur Foundation Fellowship, the Chemistry for the Future Solvay Prize, among many others. 

Daniel Chen, MD, PhD, Chief Medical Officer, IGM Biosciences 
Daniel Chen, MD, PhD, is the Chief Medical Officer for IGM Biosciences, and former Vice President, Global Head of Cancer Immunotherapy Development at Genentech/Roche. He received a BS degree in Biology from the Massachusetts Institute of Technology (1990), a PhD in Microbiology & Immunology (1996) and MD (1998) from the University of Southern California. Daniel completed an Internal Medicine Residency and Medical Oncology Fellowship at Stanford University (2003). He went on to complete a Post-doctoral fellowship with Mark Davis in Immunology, where he was a Howard Hughes Medical Institute Associate. He also ran the metastatic melanoma clinic at the Stanford Cancer Center from 2003-2006. In that time, he studied human anti-cancer immune responses pre- and post- cancer vaccination and cytokine administration to determine why anti-tumor immune responses were not more clinically effective. He received a U19 grant to develop better immunologic tools to interrogate human immune responses and ultimately patented the MHC cellular microarray to detect and functionally characterize antigen-specific T cell states. He continued as Adjunct Clinical Faculty at Stanford from 2006-2016, where he cared for melanoma patients. At Genentech from 2006-2018, Daniel focused on the clinical development of anti-angiogenic and immune modulatory targeted therapies in both early and late Development, as well as the diagnostic tools to aid their development. This included leading the clinical development for atezolizumab, a PD-L1 inhibitor, from the time the program was in research through IND, Phase I, Phase II, Phase III, to filing and approvals in multiple indications world-wide. At IGM, Daniel focuses on the development of novel engineered multivalent and multispecific therapeutics. He is a reviewer for Nature, Immunity and Clinical Cancer Research, serves on the Board of Directors for SITC, co-chair of the CRI cancer Immunotherapy consortium, gave the keynote presentation at the AACR NCI EORTC Annual Meeting 2014 and presented at the US Congressional Briefing on Immuno Oncology in 2017. He has continued to publish with academic and industry collaborators in the field of cancer immunotherapy, including the often-referenced Chen and Mellman manuscripts, “Elements of cancer immunity and the cancer-immune set point” and “Oncology meets Immunology: The Cancer-Immunity Cycle.”
