Interview with Aubrey de Grey by Jonathan Despres. Go to the Interviews. My original training was in computer science, but I've worked on aging for about ten years. My main project is "Strategies for Engineered Negligible Senescence" (SENS), a multi-part scheme to postpone aging indefinitely. My main goal is to demonstrate the feasibility of SENS by achieving what I call "Robust Mouse Rejuvenation" (RMR) -- reproducibly trebling the remaining lifespan of naturally long-lived (three years average lifespan) mice with therapies begun when they are already two.
