INRIA Grenoble is represented by the NANO-D team, which aims at developing efficient computational methods for modelling and simulation of complex nano-systems, both natural and artificial. In particular, the group develops novel multiscale, adaptive modelling and simulation methods, which automatically focus computational resources on the most relevant parts of the nano-systems under study. NANO-D is led by Stephane Redon, a specialist in virtual environments, collision detection, haptics, motion planning, simulation levels of detail, and includes several engineers and PhD students along with another permanent member, Sergei Grudinin. NANO-D develops SAMSON, a software platform for modeling and simulation of nanosystems (SAMSON stands for “Software for Adaptive Modeling and Simulation Of Nanosystems”). SAMSON integrates all the algorithms developed in the group. This group has a broad expertise in software development of big modular platforms plus a comprehensive knowledge of multiscale modelling and simulation techniques for nano- and bio-systems. Therefore, participation of this group is complementary to other teams and will provide its knowledge-base and its insights into the project.
