Dr. Marc Dupuis is a consultant specialised in the applications of mathematical modelling for the
aluminium industry since 1994, the year when he founded his own consulting company GeniSim Inc
(www.genisim.com). Before that, he graduated with a Ph.D. in chemical engineering from Laval
University in Quebec City in 1984, and then worked ten years as a research engineer for Alcan
International. His main research interests are the development of mathematical models of the Hall-
Héroult cell dealing with the thermo-electric, thermo-mechanic, electro-magnetic and hydrodynamic
aspects of the problem. He was also involved in the design of experimental high amperage cells and
the retrofit of many existing cell technologies.
Dr. Alton Tabereaux is a technical consultant in resolving issues and improving productivity at
aluminum smelters since 2007. He graduated with a PhD in Chemistry from the University of
Alabama in 1971 and then worked for 33 years as a manager of research and process technology for
both Reynolds and Alcoa Primary Metals. He was Recipient of JOM Best Technical Paper Award in
1994 and 2000, editor of Light Metals in 2004 and received TMS Light Metals Distinguished
Service Award in 2007. He is a lecturer at the annual International Course on Process Metallurgy of
Aluminium held in Trondheim, Norway and an instructor at annual TMS Industrial Aluminum
Electrolysis Courses. He has published over 65 technical papers and obtained 17 US patents in
advances in the aluminum electrolysis process.
