Grant Allen is a Professor in the Department of Chemical Engineering and Applied Chemistry at the University of Toronto. His area of research interest is in bioprocess engineering, with particular application to the treatment of aqueous and gaseous emissions and utilizing wastes for energy and chemical production. He has over 120 publications and has supervised over 30 doctoral students and 40 masters theses. He has led several environmental research consortia involving faculty and students from a range of disciplines and industrial partners from Canada and around the world (USA, Brazil, Japan, NZ). He has served in many leadership roles at UofT including as Director of the Pulp & Paper Centre from 2001 to 2003, Vice-Dean (Undergraduate) for the Faculty from 2007 to 2011 and he served as Department Chair from 2011 to 2021. He was also President in the Canadian Society for Chemical Engineering in 2008/09 and Chair of the Chemical Institute of Canada in 2019/20. He spent his research leave in 1994 with Weyerhaeuser Co. in Tacoma WA, working on biofiltration of air pollutants from wood products emissions. In 2011, he spent a research leave at a SCION, a crown research organization in New Zealand, working with their green processing team on waste management in future biorefineries.
