Marc Baaden, research director at the CNRS in Paris, is a computational chemist working in the field of structural bioinformatics. His research focuses on interactive molecular modeling approaches for biological systems and has included virtual reality approaches since 2007, then Citizen Science, and more recently the Internet of Things. He develops scientific visualization approaches as well as original tools related to Big Data and immersive analytics using virtual reality equipment. Using the Unity game engine, he has designed the UnityMol platform as a development framework for academic contexts and for collaboration with industry partners and the public. His research combines simulations of biological macromolecules and bioinformatics with high-performance computing, virtual reality, visualization, and dissemination activities
