Eloise Ann Marais is a Chemist and Professor at University College London. She leads the UCL Atmospheric Composition and Air Quality group, which develop complex models to understand human influence on air quality.
Early life and education
[edit]Marais is from South Africa.[1] She studied chemistry and applied chemistry at the University of KwaZulu-Natal for her undergraduate degree,[1] before moving to Rhodes University for an MSc in physical and analytical chemistry. was awarded an International Fulbright Science and Technology Award and completed her doctorate at Harvard University. Her doctoral research considered the removal and photocatalysis of 4-Nitrophenol using metallophthalocyanines.[2] After completing her doctorate Marais spent two years at Harvard as a postdoctoral researcher. She joined the University of Birmingham in 2016, where she developed tools for air monitoring in urban environments.
Research and career
[edit]In 2018 Marais joined Leicester as an associate professor.[3] She spent two years in Leicester before moving to University College London, where she established the Atmospheric Composition and Air Quality research group. Marais studies the impact of fossil fuel emission on human health.[4] Her research has shown that fossil fuel emissions accounted for 18% of deaths around the world in 2018, and that regions with the highest concentrations of fossil fuels in the air had the highest rates of mortality.[4]
She was awarded a European Research Council grant to understand the tropopause using multi-modal data.[1] There are uncertainties in the composition of the tropopause, and limited understanding of how it effects air quality.
She has studied how space tourism impacts the climate.[5] She ran a 10-year simulation to understand how rocket emissions compared with traditional sources of carbon dioxide, finding space tourism undermined environmental efforts on planet Earth.[5] Her research showed that a SpaceX launch emitted one hundred times more carbon dioxide than a traditional transatlantic flight,[6][7] and that these pollutants could destroy the ozone if injected into the stratospheric ozone layer.[5][8] She showed that this could persist for two or more years.[9]
She has an ongoing project that measures the atmosphere above Central London, which develops inventories and data sets.[10] She worked as a researcher in residence with the Connected Places Catapult, where she developed tools to better understand the city environment.[11] She has used Multi-Axis Differential Optical Absorption Spectroscopy to evaluate the presence of nitrogen dioxide and formaldehyde.[12] Marias was supported by the Department for Environment, Food and Rural Affairs to understand air pollution above Leicester. In 2024 she was promoted to Professor at University College London.
