Publications
Biography
Gregory Patience is a Canada Research Chair and Professor of Chemical Engineering at Polytechnique Montréal. Elsevier published his textbook on experimental methods and the Canadian Journal of Chemical Engineering has publised close to 50 peer-reviewed articles. His second book - Communicate Science Papers, Presentations and Poster Effectively - Elsevier promoted as one of the top 10 reference texts every graduate student should own. This book also served as the basis for two dozen articles on writing and ethics in the same journal. His article on ethics and authorship was viewed more than 20,000 times in 2019 in the first period following its publication in 2019 (Intellectual contributions meriting authorship: Survey results from the top cited authors across all science categories:https://journals.plos.org/plosone/article?id=10.1371/journal.pone.0198117). Nature News featured it in 2018 (Who gets credit? Survey digs into the thorny question of authorship:https://www.nature.com/articles/d41586-018-05280-0).
His laboratory has integrated mechano-chemical techniques to reduce processing times to produce powders. He has introduced ultrasonic probes into media mills with 2 mm zirconia beads. It also has spray-drying capacity ranging from bench scale (150 mm in diameter) to the pilot-scale (800 mm in diameter) with a drying capacity of 10 kg h-1). Much of the equipment was purchased with a grant from the Automotive Partnership to produce LiFePO4 cathode materials for Libatteries. He is developing catalytic processes to convert biosubstrates into value-added chemicals and fuels: one application involves atomizing low-volatility compounds - fructose, glucose, HMF, DFF, vegetable oil, glucose, lignin - in fluidized beds operating at over 150 oC.
Professor Patience began his career at DuPont in 1990 after obtaining his PhD from Polytechnique de Montréal. He resided in Wilmington, DE (USA) until 1996, then moved to Asturias, Spain, for 4 years, followed by another 4 years in Geneva, Switzerland, before returning to Canada in 1994. He obtained a Bachelor of Science and a Master of Science from the University of Calgary. His alma mater awarded him the alumni technical achievement award in 2020 and the OIQ selected him for the Honoris Genius—Social Engagement prize in 2022. In 2023, the Chemical Institute of Chemistry elected him as fellow of the institute.

Other achievements
Founded Patience Enterprises Group, Inc.
Fellow, Chemical Institute of Canada, “The Fellowship is a distinguished class of membership that recognizes CIC members who have made, and continue to make, major contributions to the chemical engineering profession”
Honoris Genius—Social Engagement, Ordre des Ingénieurs du Québec, Professor Patience’s sustainable project to fight malaria focused on disease prevention rather than treatment. He introduced Nepeta Cataria to Burundi that produces nepetalacone in trichomes that is an effective mosquito repellent(the hydrogenated form is best). The NGO ACECI has built an eco-village in Burundi
Schulich Technical Achievement Alumni Award, University of Calgary, Professor Patience patented a micro-refinery processes to reduce methane emissions economically. In the first step oxygen partially oxidizes methane to CO and H2 at 2 MPa and 1000 C. In the second step, Fe and Co catalyst recombine the CO and H2 to long chain hydrocarbons
