With the world facing a climate crisis due to the effects of anthropogenic CO2 emissions and associated global warming, key scientific research is required to aid reducing the impact society has on the environment.
The Sustainable Cements Group (SCG) at Princeton University is a multi-disciplined research group addressing the sustainability challenge facing cementitious materials and related systems. The main focus of the group centers on understanding and optimizing engineering and environmental materials, with an emphasis on controlling the chemical mechanisms responsible for formation and long-term degradation of sustainable cements. Other areas of research include conventional cements, new materials for carbon dioxide capture and utilization, industrial waste recycling, and fundamentals of silicates dissolution. This research spans multiple length and time scales, utilizing advanced synchrotron and neutron-based experimental techniques, and simulation methodologies founded at the nanoscale. A component of Dr. White’s research involves technique development (experiment and simulation) and advanced data analysis methods, including synchrotron-based micro-pair distribution function analysis and coarse-grained simulation methods.
Associate Professor Claire White leads the Sustainable Cements Group (SCG) at Princeton University. The group is situated in the Department of Civil & Environmental Engineering and the Andlinger Center for Energy and the Environment.
September 2020 – There is a postdoc opening focused on the dissolution of silicate minerals in subsurface conditions relevant to CO2 storage. More details can be found at: https://www.princeton.edu/acad-positions/position/17421. Start date within the next couple of months.

Check out the article which uses the energy industry as an example of how multiple technologies are being used to reduce CO2 emissions, and compares and contrasts this industry with the concrete industry.
