David O. Scanlon is Lecturer in Computational, Materials and Inorganic Chemistry at UCL and at Diamond Light Source. His primary research interests and experience are in the electronic structure and defect chemistry of emerging materials for a wide variety of applications, including but not limited to: transparent conducting oxides (TCOs), photovoltaics (PV), photoelectrochemical (PEC) water splitting, solid state lighting, X-ray and γ-ray radiation detectors, Li-ion batteries, catalysis and topological insulators. A recurring theme in his research is the use rational chemical design to predict the properties of novel inorganic solids for the above applications, and then the full electronic structure and defect chemistry characterization of these materials to test their application suitability. He has worked at UCL since 2011, firstly as a Ramsay Memorial Fellow (2011-2013), and since 2013 as a Lecturer. Prior to moving to UCL, David completed his undergraduate degree in Computational Chemistry in Trinity College Dublin (TCD) in 2006, and then joined the research group of Professor Graeme W. Watson in TCD where he graduated with his PhD in 2011.
