Curriculum Vitae

Funded PhD studentship
The project A Stochastic Lagrangian Scheme for Parametrizing Cloud Micro- and Macro-physics in the Unified Model is now open for application through the NERC Panorama DTP. This PhD studentship receives additional funding from a CASE award made by the Met Office. For full project description and how to apply, visit the DTP website here.
