Current activities

Glenn is the manager of the Unified Model Technical Infrastructure team. The team is responsible for the development, delivery and support of the Unified Model infrastructure and the integration of scientific developments into stable code releases. This development work is vital to enable the pull-through of scientific advances in both climate and weather prediction and to take advantage of steadily increasing supercomputer power.

His main responsibilities include:

  • Plan and manage projects to deliver stable Unified Model releases for use by both the Met Office and external Unified Model collaborators.
  • Liaise with both technical specialists and scientists across the Unified Model user community, both within and outside the Met Office, in order to guide both the short-term development and long-term strategic direction of the  Unified Model.

  • Develop and maintain robust procedures for the management, development and testing of code changes and ensure that those procedures are adhered to.

Career background

Glenn joined the Met Office in 1997. He has worked in a number of research and development areas. He initially joined Dynamics Research and testing the Unified Model dynamical core.

In 2000 Glenn moved to join the Forecast model development and diagnostics team to work on Met Office Numerical Weather Prediction models Model Development. His work included setting up operational global model configurations and rapid response regional models. For example, in response to the Boxing Day Tsunami to provide forecasts for aid relief and piloting a dust storm forecasting capability.

In 2007 Glenn joined UM External collaboration to support the use of the Unified Model by external partners. In 2008 Glenn was given a temporary 6 month role; HPC Replacement Project Manager, overseeing the procurement and evaluation of the replacement Met Office supercomputer and took up his current management position in late 2008.

Before joining the Met Office Glenn completed a PhD in Applied Mathematics at the University of Exeter, where he also undertook a BSc in Mathematics.
