Career

Dr. Virgil OPTASANU (1972), PhD. (Poitiers University, jan. 2000) ; ATER at the Bordeaux University 1 (1999-2000); since oct. 2000 Senior Lecturer at the Burgundy University, IUT de Dijon, Mechanical Engineering Department. Research field (numerical modelling and experimental works) at ICB UMR 6303 CNRS / Burgundy University on multi-physics coupling: mechanics / thermal / diffusion / chemical reaction and on the influence of the mechanical surface treatments on the corrosion of metals.
