The Atmospheric, Planetary and Theoretical Chemistry (APTC) group hosts one of the largest kinetics groups in the world, underpinning applications in sustainability, energy storage, alternative fuels, air quality, climate change and astrochemistry, and with extensive activities within the National Centre for Atmospheric Science (NCAS). The group has a unique capability and expertise in atmospheric fieldwork, laboratory and theoretical studies of processes, and numerical modelling from the Earth’s surface to the edge of space and astrochemical environments. We are working in emerging areas of renewable fuels, exoplanet discovery, space debris and space weather, plasmas and high-temperature chemistry and the development of methods which can treat large quantum systems. We have strong collaborations across the University via the Priestley Centre for Climate Futures, the Institute for Climate and Atmospheric Science, and the School of Physics and Astronomy, as well as nationally and internationally to foster interdisciplinary research and innovation in atmospheric and planetary chemistry.
