Guang Zeng obtained her PhD from the University of Leeds, UK, in 1997. After a short stint at the University of North Carolina at Chapel Hill, she joined the Centre for Atmospheric Science at Cambridge University, UK in 1998. At Cambridge, she pioneered chemistry-climate modelling, investigating the impact of climate change on tropospheric ozone and its budget using the Unified Model coupled to a detailed tropospheric chemical scheme. Since joining NIWA in 2008, Guang has taken an interest in understanding drivers of key trace gas changes in the Southern Hemisphere, using the model and long-term ground-based observations, especially those taken at Lauder, Baring Head, and Arrival Heights. Over the years, Guang has participated in several coordinated international chemistry-climate modelling evaluations in support of the IPCC Fourth and Fifth Assessment Reports, the UNEP Report on Hemispheric Transport of Air Pollutants, the 2018 Tropospheric Ozone Assessment Report, and the Chemistry-Climate Model Initiative informing the 2018 WMO Ozone Assessment. Guang's current research focus is on the impact of climate change on long-term atmospheric composition change, ozone-climate links, and global chemistry-climate model development. She has led NIWA's involvement in the AerChemMIP model intercomparison project informing IPCC AR6. She is a co-author of the 2022 WMO Scientific Assessment of Ozone Depletion.
