Biography -

Dave received a BA and M.Sci. in Natural Sciences from Robinson College, Cambridge in 2007. He was awarded a PhD in Chemistry from University College London (UCL) in 2011, working in the group of Prof. Geoff Thornton. Following post-doctoral research at UCL (2011-2014), and at Brookhaven National Laboratory (2015-2016) developing in-situ characterisation methods for model heterogeneous catalysts under Jose Rodriguez, he joined B07 in 2017 as a beamline scientist. His research interests include fundamental oxide surface structure and reactivity, and the development of novel microscopic and spectroscopic experimental techniques.

Dave’s research interests lie in the behaviour of surfaces and nanostructured materials. The motivation for this work lies in combatting global challenges such as climate change and developing clean energy sources, via improvements to heterogeneous catalysis. By forming an understanding of their behaviour at a fundamental level, it is hoped that more efficient and cheaper catalysts can be found, as well as providing interesting insights into their mechanisms of action.
 
With a background in the study of reducible metal oxide (TiO2 and CeO2) single crystals, ultrathin films, and nanostructures using imaging techniques such as scanning tunnelling microscopy (STM), non-contact atomic force microscopy (NC-AFM), and low-energy electron diffraction/microscopy (LEED/LEEM); as well as x-ray photoemission spectroscopy (XPS) and near-edge x-ray absorption spectroscopy (NEXAFS) under ultra-high vacuum, recent research has been focussed on more industrially-relevant conditions. Technological advancements and the development of commercial ambient pressure STM and XPS/NEXAFS instruments both lab-based and at international synchrotron facilities have permitted the in-situ study of model catalyst systems under high gas pressures, yielding new insights into the interactions of molecules with the surfaces of interest.
 
The combination of microscopic tools and spectroscopic analysis has been a theme of this research, with extensive use of techniques such as x-ray photoemission electron microscopy (XPEEM) which can provide spatially-resolved chemical, electronic, and magnetic information about the samples under investigation.
