Contact Dr Alfred Mayhew
Background
Dr Alfred Mayhew is an atmospheric chemist studying atmospheric oxidation processes and their impacts on air quality and climate. He obtained his PhD from the University of York and previously held a position as a Postdoctoral Research Fellow at the Wilkes Center for Climate Science and Policy at the University of Utah, USA.
Current activities
Alfred is currently working at Cranfield to develop an instrument capable of making long-term OH reactivity measurements in the remote atmosphere as a means to better monitor the behaviour of short-lived climate forcers such as methane, as well as probe our understanding of underlying oxidative processes. His previous research has focused on the oxidation of VOCs in both polluted and remote environments, with a focus on biogenic volatile organic compounds (BVOCs) such as isoprene and their potential to form Secondary Organic Aerosol (SOA). Alfred's work has spanned a range of experimental and modelling techniques including: 0-D box modelling of laboratory experiments and ambient environments, chamber experiments, global chemical transport modelling (GEOS-Chem), chromatographic analysis of ambient filter samples, and novel instrument development.
