Research Scientist

Current work and responsibilities

I am currently working on the Volcanic Ash Operational Improvement Project. My research is focussed on the use of satellite data for optimal estimation of volcanic ash dispersion model source parameters and in the calibration of probabilistic volcanic ash forecast models. This research is aimed to support the provision of better guidance tools for our volcanic ash forecasters in the form of fully quantitative predictions of the ash mass load field and its associated uncertainties.

My other research interests are on the use of inverse modelling techniques for climate change attribution studies, statistical dynamical subgrid–scale parameterisations for atmosphere and ocean climate models, and the dynamics of blocking.
