“On behalf of my fellow directors, I am delighted to welcome Dr. Ramachandra to the Lyell Board,” stated Rick Klausner, M.D., chair of Lyell’s Board of Directors. “Dr. Ramachandra’s experience and passion for developing innovative therapies for patients will help guide us as we integrate our two organizations and advance a pipeline of next-generation CAR T-cell therapies.”
