Prof. Theodore Hanein

Prof. Theodore Hanein

His vision is simple but radical: a mobile system that can travel to devastated areas and turn rubble back into high-quality construction materials, proving that "we can theoretically get it all back" – the cement, sand, aggregates and water. Prof. Hanein is a UKRI Future Leaders Fellow on Green, Circular, and Smart Cement Manufacture. Following his two UG degrees in Chemistry and Chemical Engineering, he graduated from the University of Manchester (2012) with a Masters in Advanced Process Design and Integration, and then from the University of Aberdeen (2016) with a PhD in Cement/Clinker Thermochemistry. Following graduation, Prof. Hanein began working at the University of Sheffield on low-carbon cement and concrete, where he was promoted twice from postdoc to assistant professor and then associate professor, before joining University of Leeds. His work centres around sustainable materials and processes.
