Vincent Acary<\/a> is research director at Inria, Universit\u00e9 Grenoble Alpes | TRIPOP<\/a> team. His research focuses on modeling, analyzing, and simulating nonsmooth dynamical systems, with applications in mechanics (impacts, contact, friction) and engineering (robotics, electrical circuits). He has contributed significantly to time-integration methods for these systems, particularly those involving unilateral constraints and Coulomb friction. He is a key contributor to Siconos<\/a>, an open-source platform for simulating nonsmooth systems. He collaborates with industrial partners to apply his research to real-world problems, including robotics and mechanical systems with frictional contacts. He is also the founder and editor of the Journal of Theoretical, Computational and Applied Mechanics<\/a>.<\/p>\n \n <\/div>\n <\/div>\n\n

\n \"Thierry\n <\/div>\n
\n
Thierry Faug<\/h5>\n

\n\n INRAE | IGE ECRINS<\/a> and Inria | TRIPOP<\/a>\n <\/p>\n

Thierry Faug’s research focuses on the physics and mechanics of complex-fluid flows (granular materials, snow) and their interaction with obstacles, drawing on theory, laboratory and field experiments, and numerical modelling. The main goal is to develop tools and methods that improve our understanding, prediction, and mitigation of rapid gravity-driven flows such as snow and ice avalanches or landslides. He directly applies these tools and methods in expert assessments and consultancy work for various partners, particularly in the area of avalanche protection.<\/p>\n
