Sebastien Langlois received his Ph.D. from Université de Sherbrooke, Canada in 2013 and his B. Eng. and M. Eng. in Civil Engineering from McGill University, Canada in 2005 and 2007 respectively. He is a registered professional engineer in the province of Québec, Canada. Since 2014, he is an Assistant Professor in the Civil and Building Engineering Department at Université de Sherbrooke. His main research interests are the behavior of transmission line towers, the evaluation of conductor oscillations and damages, and the effect of wind on structures. He is the principal investigator for the research partnership with Hydro-Québec and RTE(France) on structural and mechanical aspects of power transmission lines. Prof. Langlois is supervising or has supervised the research work of more than 20 Master and PhD students and is the coauthors of more than 35 scientific publications. He also has two years of experience in a consulting company in the field of transmission line structural design. He is an active member of CIGRÉ TAG 06 Mechanical behaviour of conductors and fittings.
Pierre Van Dyke received his engineering degree and his M.A.Sc. in 1983 and 1985, respectively, from École Polytechnique de Montréal, Canada. He completed a masters certificate in project management at Laval University, Canada in 2005 and a Ph.D. at Université de Sherbrooke, Canada in 2007. He is a registered professional engineer in the province of Québec, Canada.
After working in the field of vibrations at the Quebec Industrial Research Center (CRIQ), he joined the Hydro-Québec Research Institute (IREQ) in 1990, where he is senior research scientist. His fields of interest are galloping, aeolian vibrations, wake induced oscillations as well as conductor self-damping, fatigue, aerodynamics, and ice accretion. He has conducted many studies on a full-scale overhead test line and a laboratory test span. He also developed the Hydro-Quebec vibration damper, interphase spacer and elastomeric suspension clamps that are sold throughout the world.
He is currently convenor of the CIGRE Technical Advisory Group B2.06 ‘Mechanical behaviour of conductors and fittings’ and Canadian representative of CIGRE B2 overhead lines.
He has organized or been involved in the organization of conferences related to overhead line dynamics, he has also been invited speaker and chairman, and is the author or co-author of 3 book chapters, more than 50 papers and 2 patents.
