Core Development Team
The core group is responsible for putting together the component models, applying and (with the wider community) evaluating UKESM. We are:
Colin is a Professor in the School of Earth and Environment at the University of Leeds and a NCAS core scientist. He heads the joint Met Office/NERC UKESM project. In his role as head of the UKESM project he is based at the Met Office in Exeter where the bulk of the UKESM core group are located. His primary role is to lead development of the next generation of UK Earth system models, with the 1st version of UKESM targeted for application within the WCRP 6th Coupled Model Intercomparison Project (CMIP6).
Jeremy is the lead computational scientist for the UK Earth System Model (UKESM). This includes management of the software engineers who are working on the development of the model and its infrastructure, with a particular focus on the optimisation of the model to ensure that it runs efficiently. Jeremy also liaises with technical collaborators who are developing UKESM components and system enhancements, and coordinates technical support for external UKESM development and applications.
Jane is a senior research scientist at the Met Office Hadley Centre working in development and evaluation of the aerosol component UKCA-mode and its interactions within the fully coupled UKESM model. Her current work focuses on improving the simulation of aerosols and their feedbacks within the fully coupled model. Jane is currently implementing the state-of-the-art aerosol and chemistry model, UKCA-mode in UKESM replacing the older CLASSIC scheme used in HadGEM2-ES. Jane’s areas of expertise include: atmospheric modelling; aerosol feedbacks on weather and climate; climate and NWP model development and evaluation; and technical aspects of running the unified model.

Robin is a UKESM Core Team Developer and NCAS-Climate core staff. His research interests are: Earth System model development, Ice-sheet--Climate interactions, Stability of the Atlantic meridional overturning circulation
Paleoclimate, especially the glacial cycles of the last million years, and Geoenginering.Antony joins the UKESM Core Group as part of the BAS contribution to the UKESM project. He will be involved in the development, testing and evaluation of the sub-iceshelf capability of NEMO to enable its coupling with the
ice sheet component within the UKESM. Prior to joining BAS, Antony was with the NOC Southampton where his main responsibility was to support the ocean modeling capability within the Marine System Modelling (MSM) group such as running, testing and developments of some components in the NEMO ocean model. He was also involved in the preparation and testing of JOMP GO6 one-degree configuration.Rob joins the UKESM Core Group as part of the NCEO contribution to the UKESM Long-Term Science Multi-Centre project. He will be involved in the evaluation of UKESM as well as coordinating between the UKESM team and the wider NCEO/remote sensing communities.
Rob’s background is in the generation of atmospheric concentrations of key climate-relevant species, particularly CO2 and CH4, from remote sensing data. He is currently approaching the end of a European Space Agency Living Planet Fellowship where he has investigated the temporal/spatial distributions of these greenhouse gases, identifying anomalies and linking them to the key geophysical drivers.Lee is a marine ecosystem modeller with an interest in the development, evaluation and validation of global scale models. Lee leads the marine model evaluation toolkit development for the UK Earth System Model.
As a member of the UK Ocean Biogeochemistry Network Model Inter-comparison Experiment, iMarNet, Lee coupled the ERSEM model to NEMO in the global settings to allow the comparison of UK biogeochemical models coupled with the same underlying physics. Lee also used this model to investigate the use of emergent properties as a method to evaluate the performance of marine ecosystem models.
Outside of model development, Lee has also contributed to a range of shorter projects, including studies on the impact of leaks in carbon capture and storage sites in the North Sea, and a pilot study which pioneers the use of surfers as a platform for collecting data in the near shore environment.Julien is a marine systems modeller in UKESM, member of the National Oceanography Centre (NOC) based in Southampton.
Andrew is a marine systems modeller in UKESM, member of the National Oceanography Centre (NOC) based in Southampton. Andrew’s interests are on: global-scale plankton ecosystem modelling, biogeochemistry of the ocean's carbon cycle, the role of nitrification in the ocean's nitrogen cycle, geoengineering, and diatom ecology and the ocean's silicon cycle.

- Marc StringerCoupling and OptimizationNCAS, based at the Met Office Hadley Centre, Exeter
As of June 2014, Marc is a computational scientist working in the core team responsible for setting up UKESM1, the next generation UK Earth System Model. Employed by NCAS-Climate (University of Reading), funded by NERC, and based at the Met Office in Exeter.
Before joining the UKESM team, Marc worked in the department of Meteorology at the University of Reading from the start of 2001 until the end of May 2014. Richard is an Expert Scientific Software Engineer working in the UKESM Core team. The current focus of Richard's work is on planning, development, performance analysis and optimisation of coupled Atmosphere-Ocean-Sea Ice models and their components in the context of multiple program multiple data (mpmd) systems. A particular challenge is the move to develop mechanisms to allow coupling of 3D fields between various model components. New generations of coupled models will place increasing demands on computing resources, as higher resolution multi-component models are developed and deployed. Richard is working to ensure that the infrastructure to run large parallel models is available and that those models continue to be technically and scientifically viable on state-of-the-art supercomputing platforms.

- Stephen PringCoupling and OptimisationMet Office Hadley Centre, Exeter
Stephen joined the UKESM core group in February 2020 as a scientific software engineer. Prior to this Stephen worked in Dynamics Research at the Met Office between 2015-2019. During this time Stephen worked on developing the next-generation dynamical core called GungHo. Designed to be more scalable than the current dynamical core ENDGame within the UM, GungHo uses a cubed-sphere mesh rather than a latitude-longitude mesh to avoid singularities at the poles. Before this Stephen worked in Data Assimilation between 2010-2014. Here Stephen worked on developing the ensemble-variational ensemble generation system which is now being used operationally at the Met Office for generating the forecast ensemble members.
