Structural biologist and Nobel Laureate in Chemistry in 2009, awarded for his discoveries on the structure and function of ribosomes. His research provided crucial insights into how ribosomes synthesize proteins, a process vital to cellular health. His work has important implications for longevity, as it helps maintain cell health and prevent age-related diseases. Currently a professor at the University of Cambridge and a member of the Royal Society, Ramakrishnan continues to investigate how cellular mechanisms influence longevity and long-term health.
