I'm a titular Professor of Planetary Physics at the University of Oxford in the Department of Physics, specifically the sub-department of Atmospheric, Oceanic, and Planetary Physics. I have over 30 years experience in remote sensing of planetary atmospheres from satellite observations, and more recently ground-based observations, and am the principal author or co-author of over 250 papers published in the open scientific literature. My main research interests are: 1) Radiative transfer modelling of the planetary atmospheres using thermal emission and scattering models; and 2) Development and application of multivariate retrieval methods, in particular the NEMESIS code. I was a member of the Galileo Near Infrared Mapping Spectrometer (NIMS) science team and a Co-Investigator of Cassini Composite Infrared Spectrometer (CIRS). I was also a Co-Investigator of the Visible Infrared Thermal Imaging Spectrometer (VIRTIS) on ESA ROSETTA and Venus Express missions, and was a Consultant Scientist to the Long Wave Spectrometer team of the Infrared Space Observatory. I have been involved with several ground-based observation campaigns using UKIRT, Gemini and VLT and have taken a particular interest in monitoring the changes in Uranus' cloud structure during and after its northern spring equinox in December 2007. More recently atmospheric spectra of exoplanets and am also studying the atmospheres of Venus, Mars, Jupiter, Saturn and Neptune. Most recently I have been working with several colleagues on reanalysing phase curve observations of WASP-43b using a novel 2.5-D retrieval model.
