I am an Emeritus Professor and part-time researcher in the Department of Physics, and Emeritus Fellow and former Tutor in Physics at Trinity College, University of Oxford, UK. Although semi-retired, in the Department I lead the Geophysical and Planetary Fluid Dynamics group, in which we investigate the fundamental dynamics underpinning the circulations of planetary atmospheres and oceans. This entails a combination of the analysis of spacecraft observations of (mostly Solar System) planetary atmospheres, numerical circulation modelling and laboratory experiments on rotating, stratified flows.
At the moment I am working on investigating the turbulent exchange of energy within the atmospheres of Jupiter and Saturn (using data from the Cassini mission) and dynamical processes in turbulent convective flows in laboratory experiments carried out in Oxford and Turlab at the Università degli Studi di Torino, Italy (http://www.turlab.ph.unito.it/#).
Until April 2019 I was also the Joint Chair of the Oxford-Met Office Academic Partnership, which was launched formally in October 2013. In this role I worked with various colleagues across the whole of the University to promote stronger links and collaboration between Oxford researchers and the Met Office and its other academic partners. In practice, this is mainly focused on various aspects of climate science and its applications. The current Joint Chair is Tim Woollings - see http://www.climate.ox.ac.uk/oxford-climate-research/met-office-academic-...(link is external) for more details.
