Robert Coffman, Ph.D.
Robert Coffman, Ph.D., is a consultant in the vaccine field and an adjunct professor in the Department of Biomolecular Engineering and the Genomics Institute at the University of California, Santa Cruz. Dr. Coffman retired as Dynavax’s Chief Scientific Officer in 2019. In that role, he led the discovery and development of novel vaccine adjuvants and therapeutic agents that target toll-like receptors, and helped guide the development and U.S. Food and Drug Administration (FDA) approval of HEPLISAV-B®, the company’s differentiated vaccine for hepatitis B, and its proprietary CpG 1018® adjuvant, which is now used in multiple vaccines. Prior to joining Dynavax, Dr. Coffman was a founding member of the DNAX Research Institute, where with Dr. Tim Mosmann, he made key discoveries including defining the two principal subtypes of helper T cells (Th1 and Th2) and the basic mechanisms of T cell regulation in asthma and infectious and parasitic diseases, as well as demonstrating the central role of regulatory CD4+ T cells in preventing inflammatory bowel disease.
Dr. Coffman has authored more than 200 scientific publications and is an editor of the Proceedings of the National Academy of Sciences. He is a member of the National Academy of Sciences and the American Academy of Microbiology and is a recipient of the Novartis Prize for Basic Immunology and the William B. Coley Award.
Kathryn M. Edwards, M.D.
Kathryn Edwards, M.D., Professor of Pediatrics Emerita, Infectious Diseases Division, and the former Director of the NIH-funded Vanderbilt Vaccine Research Program, Vanderbilt University School of Medicine. In her more than 40-year tenure at Vanderbilt, she led pivotal clinical trials for many vaccines and played a major role in their subsequent implementation. Dr. Edwards played a key role in the evaluation and licensure of the bacterial conjugate and acellular pertussis vaccines and in both seasonal and pandemic influenza vaccines. She remains active in assessing the safety and effectiveness of vaccines and monoclonal antibodies and in mentoring the next generation of vaccine scientists.
Dr. Edwards She has served on multiple committees of the NIH, CDC, FDA, WHO, and Infectious Diseases Society of America, including as Chair of the FDA’s Vaccines and Related Biologic Products Advisory Committee. Dr. Edwards is the recipient of the IDSA Mentor Award, the Maureen Andrews Mentoring Award from the Society for Pediatric Research, the National Foundation for Infectious Diseases Maxwell Finland award for Scientific Accomplishments, the Frank Morriss Leadership Award in Pediatrics, and the American Pediatric Society Howland Award. In 2008, Dr. Edwards was elected to the National Academy of Medicine of the National Academy of Sciences. She has over 600 publications in peer reviewed journals.
She graduated from the University of Iowa College of Medicine and completed her pediatric residency and infectious disease fellowship at Northwestern University and her postdoctoral training in immunology at Rush Medical School.
Rino Rappuoli, Ph.D.
Rino Rappuoli, Ph.D., is Scientific Director of the Biotecnopolo di Siena Foundation and head of MAD Lab Toscana Life Sciences, Italy. He is also an Honorary Professor of Vaccinology at Imperial College, London, and Senior Professor of Molecular Biology at the University of Siena. Dr. Rappuoli has introduced several novel scientific concepts and developed several licensed vaccines, including the first conjugate vaccine against meningococcus C, the MF59-adjuvanted seasonal and pandemic influenza vaccine, and other vaccines for acellular pertussis containing a non-toxic mutant of pertussis toxin, meningococcus B, respiratory syncytial virus and CRM 197 as carrier of most conjugate vaccines.
Previously, Dr. Rappuoli was Chief Scientist and Head, External R&D and at GSK Vaccines, Founder of the GSK Vaccines Institute for Global Health (GVGH), head of Vaccine R&D at Novartis, CSO at Chiron Corporation, and Head of R&D at Sclavo.
