- Profile
-
I graduated from The University of Edinburgh in 2002 with an MChem (Hons) in Chemistry and completed a PhD in heterogeneous catalysis at the University of Cambridge, Department of Chemical Engineering and Biotechnology, in 2006 under the supervision of Prof. Lynn Gladden. Thereafter, I worked as a Research Associate in the Magnetic Resonance and Catalysis group at Cambridge.
In 2009 I completed a stay as a guest scientist at the Fritz-Haber Institute, Berlin, working in the group of Prof. Robert Schlögl. In 2010 I was appointed as a University Lecturer at the University of Cambridge, moving to Sheffield as a Lecturer in 2012. I was promoted to my present position of Senior Lecturer in 2017.
My research is concerned with sustainable catalytic science and engineering, in particular the application of waste or low-value co-products as feedstocks for the production of value-added chemicals and fuels. Current areas of research span CO2 utilisation, biomass conversion, energy materials and petrochemical processing.
I am a chartered engineer, Member of the Institution of Chemical Engineers (MIChemE) and member of the Royal Society of Chemistry (MRSC).
