Donald R. Sadoway is the John F. Elliott Professor of Materials Chemistry in the Department of Materials Science and Engineering at the Massachusetts Institute of Technology. He obtained the B.A.Sc. in Engineering Science, the M.A.Sc. in Chemical Metallurgy, and the Ph.D. in Chemical Metallurgy, all from the University of Toronto. The author of over 150 scientific papers and holder of 19 U.S. patents, his research is directed towards the development of rechargeable batteries for grid-level storage and mobile applications as well as environmentally sound technologies for the extraction of metals. Inventions have migrated from his MIT laboratories to three companies: Ambri (liquid metal battery), Boston Electrometallurgical (green metals production), and SolidEnergy (lithium polymer battery). Viewed over 1,500,000 times, his TED talk from February 29, 2012 is a narrative about inventing inventors as much as it about inventing technology. In 2012 he was named by Time magazine as one of the 100 Most Influential People in the World.
