Fellow Detail

My research interests involve chemistry-climate modelling using the United Kingdom Chemistry and Aerosols (UKCA) model.

I am a member of the National Centre for Atmospheric Science and a Director of Research (equivalent to Professor) in the Department of Chemistry at the University of Cambridge. I work with the United Kingdom Chemistry and Aerosols composition-climate model, which is part of the Met Office Unified Model. I provide model development and support for others to use the model on national HPC facilities such as Monsoon2 and ARCHER2, and I run regular training events on using UKCA. I am also the Training Theme Leader for the National Centre for Atmospheric Science, with oversight of its range of short courses for environmental scientists.

As Code Owner of UKCA for the Met Office I am involved with the UM code review process and support others in committing their code back to the UM trunk. As part of ExCALIBUR I am leading a project to create standalone configurations of UKCA to facilitate the coupling of the chemistry and aerosol schemes into multiple models with a number of different applications. We are also porting UKCA to enable it to run efficiently on GPUs.

I have created UKCA configurations that are able to be run on desktops and small servers using a virtual machine environment. This can also be run on AWS and the JASMIN Unmanaged Cloud, and enables researchers to complete the UKCA training and further develop the code without needing to use HPC resources.

I perform model simulations using UKCA in support of international model intercomparison exercises such as the SPARC Lifetime Assessment, the Chemistry-Climate Model Initiative (CCMI), and the Coupled Model Intercomparison Project (CMIP6), specifically AerChemMIP.
