Franklin Hadley Cocks is Chairman of the Department of Mechanical Engineering and Materials Science at the Pratt School of Engineering of Duke University in Durham, North Carolina, USA. Professor Cocks has taught courses on energy and the environment for decades and has published over 150 technical papers and more than 20 US patents. He earned all his degrees from MIT and was a Fulbright Fellow at Imperial College, London, and a Visiting Scholar at Harvard. At Tyco Laboratories he developed the silicon ribbon crystal growth method now used to produce silicon solar cells on an industrial scale. His foamed-metal payload was flown on the Columbia shuttle in 1991. He was a consultant to Los Alamos National Laboratory for many years and more recently for the Department of Energy.
