He also served as Director, Global Regulatory Affairs for Rare Diseases and Gene Therapies at GlaxoSmithKline, where he was part of on the international regulatory team for the European approval of the gene therapy Strimvelis® for ADA-SCID, and subsequently secured Regenerative Medicine Advanced Therapy (RMAT) designation for a retinal gene therapy product.

Dr. Johnson holds a Ph.D. in Neurobiology from the University of North Carolina (UNC) School of Medicine; a Master of Business Administration from the Kenan-Flagler School of Business, UNC; and a Bachelor of Science in Chemistry from the University of South Florida.
