The Gerontology Research Group (GRG) was founded in 1990 by L. Stephen Coles, MD PhD, and other physicians and scientists at UCLA, Cal-Tech and elsewhere.  

Our mission is to slow and ultimately reverse age related decline for more healthy years of life.

GRG is the foremost authority on the world's oldest humans -- specifically supercentenarian research, authentication and database.  This division is managed by Robert Young who leads a group of international researchers.  GRG is cited by the Guinness Book of World Records and often quoted in newspapers.
