Dr. Donald Kennedy†

Founding Advisor · In Memoriam

Prior to his untimely passing, Dr. Kennedy was a founding advisor and shareholder in Riptide Bioscience, and we strive to maintain the scientific rigor and higher objectives he inspired.  Dr. Kennedy was a noted neurobiology research scientist prior to chairing Stanford University’s Department of Biology and founding its Program in Human Biology.  He went on to serve as the US FDA Commissioner, later returning to Stanford as provost and ultimately University President.  Subsequently he served as editor-in-chief of Science.

Dame Carol Black

Board of Advisors

Dame Carol Black is a world-renowned expert in rheumatology, who served as Medical Director of the Royal Free Hospital at University College London, where she established Europe’s largest center for both scleroderma research and treatment.  Later she served as President of the Royal College of Physicians, and served as the UK government’s National Director for Health and Work.  She is co-president of the UK government organization focusing on the consequences of musculoskeletal disorders, and led the government’s Independent Review of Drugs.

Dr. Frank McCormick

Board of Advisors

Dr. Frank McCormick is among the world’s top cancer researchers, and received the first Stephenson Global Prize for his groundbreaking cancer discoveries.  Dr. McCormick’s pioneering work uncovered how mutations in the KRAS gene, present in more than 90% of pancreatic ductal adenocarcinomas (PDAC), disrupt the body’s natural ability to regulate cell growth. His discoveries have been foundational to the development of therapies targeting KRAS, a goal once thought unattainable.
