Words from the Team
Brian Johnstone
Vice President, Research
For the past 20 years, Dr. Johnstone has been actively involved in translating adult stem cell therapies into treatments for a host of diseases affecting the major organs of the body. In 2004, he co-authored one of the first studies demonstrating the potential for treating cardiovascular diseases with novel adult stem cells isolated from fat. At Ossium, Dr. Johnstone leads the Research organization, driving innovation and translating scientific discoveries into practical applications that advance the company mission.
Dr. Johnstone co-founded NeuroFx, an early-stage biotech firm developing a novel therapy for neurological disorders. Dr. Johnstone led the R&D program at NeuroFx for two years, where he was directly responsible for preclinical and chemistry, manufacturing, and controls development activities. He continues to act as an advisor for NeuroFx. Additionally, Dr. Johnstone has formed two other biotech companies: Chemigen, which is developing a small molecule drug for treating Lou Gehrig’s disease, and EmphyMab Biotech (now Allinaire), which is developing biologics to treat serious lung diseases.
Before becoming an entrepreneur, Dr. Johnstone was an early employee at Sangamo Biosciences for 6 years. During this time, he managed the preclinical development program for their lead gene therapy candidate for cardiovascular diseases, which was promoted to clinical testing. Dr. Johnstone received his PhD from the University of Maryland, College Park, and completed a postdoctoral fellowship at the University of California, Los Angeles.
I was initially drawn to Ossium by Kevin's vision of changing the way we think about healthcare, and the potential to positively impact so many people. As I got to know the team, my desire to be a part of Ossium only grew! Every day I come to work energized by the passion and knowledge of those around me.
