Cowan, Alexander - University of Liverpool

个人简介

Alex obtained his PhD in Chemistry from the University of Nottingham for the study of inorganic reaction mechanisms with transient spectroscopy, under the supervision of Prof. Mike George. Following a 1 year postdoctoral position, also at Nottingham, on the photocatalytic reduction of carbon dioxide he moved to Imperial College London to study photoelectrochemical water splitting with Prof. David Klug. In 2011 Alex was appointed to a Lectureship in Renewable Fuel Synthesis at Imperial College on the Artificial Leaf programme. In October 2012 he joined the department of Chemistry and the Stephenson Institute for Renewable Energy at Liverpool University where his research interests focus on the study of catalytic systems, primarily for the production of solar fuels.
