311 Walters Hall
Obtained Bachelor’s degree in Chemical Engineering and Applied Chemistry from University of Toronto in 1982. Obtained Ph.D in same discipline from the same university in 1987. Joined the CHE Faculty as a Research Associate in May 1987. Dr. Francis obtained four GOALI Awards on non-sulfur lignin from the Chemistry Division of the National Science Foundation (NSF) during 2005 – 2013, three of the awards were on soda/quinone lignins and one on lignin precipitated from the hot water pre-treatment step (pH 3.0-3.5) in lignocellulosic ethanol production. He was the Principal Investigator and Andritz Inc. was the industrial partner on all 4 occasions.
