The Oxford Team

Myles Allen

Prof Myles R. Allen

School of Geography and the Environment, University of Oxford

Myles Allen is the founder of and was the first to propose the use of Probabilistic Event Attribution to quantify the contribution of human and other external influences on climate to specific individual weather events. He is Professor of Geosystem Science in the School of Geography and the Environment, University of Oxford and Head of the Climate Dynamics Group in the University’s Department of Physics.

Andy Bowery

Andy Bowery is the Senior Software Engineer / Systems Architect of Andy works as a researcher in the Oxford e-Research Centre, University of Oxford.

Dr Glenn Carver

Glenn is a visiting senior scientist at He retired from the European Centre for Medium-Range Weather Forecasts (ECMWF) at the end of 2021. At ECMWF he created and managed the OpenIFS programme. This developed a portable version of the ECMWF operational forecast model used by international researchers at their own institutions.  During this time, he collaborated with CPDN to provide the OpenIFS model in the CPDN BOINC framework.

Prior to ECMWF, Glenn was a research scientist at the University of Cambridge employed by the National Centre for Atmospheric Science. During his career he has carried out research and published scientific papers covering topics such as atmospheric dynamics, climate and atmospheric chemistry. He has gained extensive knowledge in the use and development of research and operational atmospheric and climate models, running on state-of-the-art high performance computers, together with  applications of scientific data in areas such as field campaigns. He maintains an interest in the application of OpenIFS@Home at by international scientists, and science communication in the community.

Sarah Sparrow

Dr Sarah N. Sparrow

Sarah Sparrow is the coordinator for CPDN responsible for work unit deployment and experiment submission and day-to-day management of the team. Sarah’s background is in atmospheric dynamics and she is interested in how large scale dynamics translates to climate impact studies. She is experienced in data driven coupling of climate model output to impact models and leads research proposals in this area. Sarah has extensive experience in preparing and analysing large ensembles of climate model output. She has tutored at several international attribution workshops and summer schools. Sarah is a senior researcher at the Oxford e-Research Centre, University of Oxford.

Professor David Wallom

David Wallom is the technical director of he leads Oxford participation in a number of climate impact projects including studies on climate effects on NW timber industry and the effects of extreme weather events on south and east Asia. He is an associate director and leader of the Volunteer Computing Group at the Oxford e-Research Centre, University of Oxford.
