Biography

Chris began his career in atmospheric science when he joined the Met Office Hadley Centre in 2003 as a member of the Climate Model Development and Evaluation group. Chris worked on a number of UM-based projects and served as Configuration Manager for the HadGEM2 project. During this time he also studied for an MSc in Weather, Climate and Modelling at the University of Reading, which he completed in 2006.

In 2007, Chris left the Met Office to undertake a PhD in cloud microphysics at the University of Manchester, involving the use of a variety of cloud process models and regional weather models, including the Weather Research and Forecasting Model.

Following his PhD, Chris remained at Manchester as a postdoctoral researcher on the NERC-funded DIAMET project. In 2014 he became a Research Fellow and worked on two EU funded projects (BACCHUS and DACCIWA), involving the use of PolarWRF and the Met Office-NERC-Cloud model respectively.

In January 2018, Chris joined CEMAC as a Software Development Scientist. He is currently working with the Met Office Unified Model on a range of technical projects.
