Biography

Gregory Patience holds a Canada Research Chair and is Professor of Chemical Engineering at Polytechnique Montreal. He published a book on experimental methods, which is now the subject of a series of several dozen articles in The Canadian Journal of Chemical Engineering, and his 2nd book – Communicate Science Papers, Presentations and Poster Effectively – Elsevier nominated as one of the top 10 reference texts every graduate student should have.  This book was also the basis of two dozen articles on writing and ethics in the same journal. His article on ethics and authorship has been viewed over 20 000 times in 2019 during the first after it was published 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).

Hisr laboratory has integrated mechano-chemical techniques to decrease the processing times to produce powders. He introduced ultrasonic probes into media mills with 2 mm zirconia beads. He also have spray drying capability from the bench scale (150 mm in diameter) to the semi-works scale (800 mm in diameter, with a drying capacity of 10 kg h-1).  Much of the equipement was purchased from an Automotive Partnership grant to produce LiFePO4 batteries. He develops catalytic processes to convert bio-substrates to value added chemicals and fuels:  One application is to atomize poorly volatile compounds – fructose, glucose, HMF, DFF, vegetable oil, glucose, lignin – into fluidized beds operating above 150 oC. Currently he has two industrial collaborations to treat end of life polymers and programs in flow chemistry for peroxides and another project on cannabis.

Prof. Patience started his career at DuPont in 1990 after completing his PhD at Polytechnique Montreal.  He resided in Wilmington, DE (USA) until 1996, then moved to Asturias, Spain for 4 years, followed by another 4-year sejour in Geneva Switzerland before returning to Canada in 1994. He completed a B.Sc and M.Sc. at the University of Calgary.
