Short Bio

Julien Pettré is research scientist at INRIA, the French National Institute for Research in Computer Science and Control (www.inria.fr) since 2006. He received M.S. degree in 2000. He prepared his thesis under the supervision of Jean-Paul Laumond and obtained his Ph.D. in 2003 from the University of Toulouse III in France. He then spent one 18 months post doc at VRlab, EPFL, Switzerland, headed by Daniel Thalmann. At INRIA in Rennes, he joined the Bunraku team headed by G. Dumont. His research interests are : crowd simulation, motion planning, autonomous virtual humans, computer animation and virtual reality.
