Présentation
Gilles Ausias is Professor of Mechanical Engineering at the Université Bretagne Sud, where he has been a member of the faculty since 1995. He joined UBS after obtaining a mechanical engineering degree from INSA Lyon in 1985 and a PhD from the Ecole des Mines de Paris in 1991, followed by 4 years as a research engineer in a company. He collaborated with Pr. J.F. Agassant - Ecole des Mines de Paris, Pr. P.J. Carreau - Ecole Polytechnique de Montreal, Pr. R.I. Tanner - University of Sydney and N. Phan-Thien - National University of Singapore. He has collaborated with various companies such as Coriolis Composites and Cooper Standard on foam and composite processing. He is co-inventor on 7 patents and co-author of over 70 papers in international journals. He is a member of the editorial board of Journal of Non-Newtonian Fluid Mechanics. His research interests are in suspension rheology and composite processing. He has developed experimental characterisation tests for suspensions, theoretical models and numerical simulations of complex fluid rheology. He is currently professor emeritus.
