I believe that one of the current challenges in computer animation is the modeling and the simulation of plausible anatomical characters.
My research focuses on technologies merging:

physics-based animation, to naturally manage the physical behavior of the human body,
soft body deformation, to take into account the continuum mechanics effects of human tissues, and
musculoskeletal simulation, to actively actuate the virtual humans through muscle forces.

My investigations mostly involve biomechanical simulations within real-time virtual environments, e.g. animation engine for games and interactive applications.
