Juine-Ruey (JR) Chen Ph.D

Dr. Chen specializes in human vaccine research and antiviral therapies. He joined the RH Biopharma in Aug 2018. He is responsible for the new vaccine candidate’s development and production. He has over 10 years of practical, hands-on industry experience on human vaccine. He was previously the Head of R&D at Adimmune Corporation, where he was committed to contribute the know-how and solutions for the new vaccine development as well as for providing the design, methods and operators for the manufacture of the vaccines. Additionally, He leaded a team to develop the EV71 vaccine produced by 200-L scale serum-free microcarrire bioreactor system for phase II and III clinical trial studies and also developed a fundamental sf9 insect cells-baculovirus expression platform to convert traditional flu vaccine from egg-based to a cell culture-based production process. Prior to Adimmune Corporation, Dr. Chen was a research scientist in Genomics Research Center (GRC), Academia Sinica (AS) focused on developing universal flu vaccine against influenza. His current work is to lead a team for developing universal flu vaccine that can provide durable protection for all age groups against multiple influenza strains, including those that might cause a pandemic.
