Centre for Atmospheric Science

Research Associate

I am a Postdoctoral Research Associate working with Professor Alex Archibald at Department of Chemistry and Centre for Atmospheric Science. My research expertise is in atmospheric chemistry and climate modelling. My research interests and experiences are

Quantifying the ocean-atmosphere sulphur cycle's contribution to the climate

My current research focuses on improving the representation of global marine sulphur cycle in climate models, utilising the  UK Chemistry and Aerosol model (UKCA) and the UK Earth System Model (UKESM). This work includes understanding new chemical mechanisms for newly discovered sulphur molecules in the marine atmosphere, such as hydroperoxymethyl thioformate (HPMTF) and CH₃SH, and incorporating these into the UKESM. This allows me to investigate how this novel chemistry influences the impact of natural marine aerosol on climate and on human-driven climate change. 

Atmospheric modelling of volatile organic compounds (VOCs)

This work focused on the development of emission profiles and chemistry module for VOCs in the atmospheric chemistry transport model of European Monitoring and Evaluation Programme (EMEP) in order to understand the roles of different VOCs in ozone and particle formation. My first-author paper on this work is published in Atmos. Chem. Phys.. Concurrently, I worked with colleagues to implement the Cloud-J photolysis rate calculation module into the EMEP model; our co-authored paper is published in Geosci. Model Dev.. Additionally, I also participated in a VOCDep project, focusing on enhancing the model parameterisation of the dry deposition processes of VOCs from the atmosphere to different land surfaces.

Global modelling of atmospheric reactive N and S

My doctoral research centred on simulating atmospheric reactive N and S species concentrations and chemistry and their mitigation at regional and global scales. By validating against measurements from different air quality monitoring networks worldwide, my work confirmed the EMEP-WRF modelling system's credibility for global budget analyses and for investigation of the effectiveness of different N and S emission control strategies. I have three first-author publications in Atmos. Chem. Phys. (2) and Geosci. Model Dev. from this work.

Analytical Method Development for aerosol N and S

This research created an innovative coupling of aerosol carbon and chemiluminescent NOx analysers capable of distinguishing between organic and inorganic nitrogen-containing species in aerosols. This work led to a co-authored paper in Environ. Sci. Technol. Additionally, I contributed to research on the kinetics of the production of SO42- from the heterogeneous OH oxidation of CH3SO4Na using an oxidation flow reactor and ion chromatography, a study that also yielded a co-authored publication in ACS Earth Space Chem..
