Leon is a surface analytical and materials’ chemist, who for the last 20 years has used various analytical techniques to investigate the structure and stability of cementitious materials. He spent a number of years applying Raman and photoelectron spectroscopies for the analysis of cement. More recently he has focussed on composition-microstructure-performance relationships in low-clinker binders.
Leon leads the Centre for Infrastructure Materials in Leeds, a part of UKCRIC. The Centre provides state of the art facilities for the characterisation of a huge suite of materials: from cement and concrete, through metals and polymers to new biocomposites. The laboratories are also fully equipped for undertaking accelerated ageing studies on this full range of materials.
Outside of construction, Leon's research extends into solidification/stabilisation of wastes within cement, and the immobilisation of low and intermediate level nuclear waste. As such, he is a member of Nuclear Leeds.
While in Leeds he has been an active participant in Nanocem. His work within the consortium has led to collaborations with the Technical University of Munich, ZAG (Slovenia), Lund University and IFSTTAR (Paris).
He is Editor of Advances in Cement Research, and serves on the Editorial Board of Cement and Concrete Research.
