Alexander (Sandy) is an atmospheric chemist who studies processes at the interfaces between solids and gas or liquids. He has worked on problems in planetary atmospheres including Venus, Titan and Earth's mesosphere, stratosphere and surface.
He has recently focussed on crystalisation in Polar Stratospheric Clouds, which relates to the formation of the ozone hole, and on developing a novel catalyst for reducing the negative air quality impacts of combustion exhaust.
Sandy has worked at the University of Leeds since starting his PhD in 2012, having been a teaching and research fellow since 2016. Based in the School of Chemistry, he collaborates widely with Schools of Physics and Astronomy, Earth and Environment and Chemical and Process Engineering.
