He was President (1997-2001) and is an Honorary Fellow of the International Congress on Fracture. He is also a Fellow of the Materials Research Society (MRS), the Institute of Physics (FInstP), the American Society for Materials (ASM), the American Society for Mechanical Engineers (ASME), the American Ceramic Society, and the U.K. Institute of Materials (IOM3). He is also a Fellow and Life Member of TMS and a chartered engineer (CEng.) in the U.K.
Dr. Ritchie received a B.A. degree (double first class honors) in physics and metallurgy in 1969, the M.A. and Ph.D. degrees in Materials Science in 1973, and the Doctor of Science (Sc.D.) degree in 1990, all from Cambridge University. Following periods as the Goldsmith's Research Fellow in Materials Science at Churchill College, Cambridge (1972-1974) and as a Miller Research Fellow for Basic Research in Science at the University of California in Berkeley (1974-1976), he joined the faculty in Mechanical Engineering at M.I.T. where he became the Class of 1922 Associate Professor in 1979. In 1981, he returned to Berkeley where he has been Professor of Materials Science since 1982. He was also Deputy Director of the Materials Sciences Division at the Lawrence Berkeley Laboratory from 1990 to 1994, and Director of the Center for Advanced Materials there from 1987 to 1995.
He has served as a consultant for both government and industry, including for Alcan, Allison, Boeing, Chevron, Exxon, GE, GM, Google, Grumman Aerospace, Instron, JPL, Northrop, Rockwell, Rolls-Royce, Sunpower, Teledyne, Westinghouse and numerous legal firms. He has also acted as a consultant in the medical field to Abbott Vascular, ATS Medical, Baxter, Cordis, Carbomedics, Edwards, Guidant, CV Medical, Medstone, NDC, Shiley, Sorin, and St. Jude Medical, on the mechanical integrity of cardiac valves, endovascular stents and other prosthetic devices.
