John F. Elliott Professor of Materials Chemistry in the Department of Materials Science and Engineering at the Massachusetts Institute of Technology. His B.A.Sc. in Engineering Science and Ph.D. in Chemical Metallurgy are from the University of Toronto. He joined the MIT faculty in 1978. The author of over 170 scientific papers and inventor on 32 U.S. patents, his research is on environmentally sound metals extraction technologies and on batteries for grid-scale storage and for electric vehicles. He is the founder of two companies, Ambri and Boston Metal. Online videos of his chemistry lectures hosted by MIT OpenCourseWare extend his impact on engineering education far beyond the lecture hall. Viewed over 2,000,000 times, his TED talk is as much about inventing inventors as it is about inventing technology. In 2012 he was named by Time magazine as one of the 100 Most Influential People in the World.
