I am a climate and weather modelling scientist currently working as “Head of science” in the Technical Support Unit (TSU) of the Intergovernmental Panel on Climate Change (IPCC) Working Group 1. The IPCC is the leading international body for the assessment of climate change. It was established by the United Nations in 1988 to provide the world with a clear scientific view on the current state of knowledge in climate change and its potential environmental and socio-economic impacts.
Previously, I worked for the African Climate Policy Centre (ACPC) of the United Nations Economic Commission for Africa (UNECA) – whereby my responsibilities gravitated around strengthening the climate science knowledge and research foundation required for delivery of reliable, detailed and accurate climate information services to support the Africa’s sustainable and low carbon development pathway in a changing climate.
In addition, I spent a decade working for the UK Met Office as Senior regional climate modelling scientist in charge of development, evaluation and dissemination of the Met Office fleet of regional climate prediction systems, and advising on their use for construction and application of climate change scenarios for impact and adaptation studies worldwide. I also worked in the Global Model Evaluation and Development (GMED) team of the Met Office where my role included designing and implementing novel diagnostic strategies to identify local and remote sources of biases in seamless global climate and weather models, understanding these biases from a process-based perspective, exploring the added value of high spatial resolution for detailed predictions (particularly over Africa, Asia and the Americas), actively contributing to the international activities in regional modelling, leading and conducting training activities worldwide, and supporting collaborators and customers on the use of climate information services.
