Franz-Josef Ulm (born March 9, 1964 in Fürth/Bavaria, West Germany) is a structural engineer, an engineering scientist and a professor since 1999. He is Professor of Civil & Environmental Engineering at the Massachusetts Institute of Technology (MIT), the Faculty Director of the Concrete Sustainability Hub (CSHub@MIT). He is credited for discovering the nanogranular structure of Calcium-Silicate-Hydrates (C-S-H), the binding phase of concrete, and for the development of concepts of nanoengineering of concrete which combine advanced nanomechanics experiments with molecular simulation results. He speaks up for an environmental sustainable engineering, with "greener" concrete with lower CO2 footprint, to reduce the carbon footprint of concrete; to enhance concrete's resilience; and reduce its impact on global warming.
