Professional biography

I am Deputy Head of Department and a Senior Lecturer in the Department of Physical Sciences at the Open University.

 

I joined the OU in October 2005, having previously held a Lectureship in Atmospheric, Oceanic and Planetary Physics, Department of Physics, Oxford University, where I remain a Visiting Fellow. I am also a Fellow of the Royal Meteorological Society.

 

My first degree was in Natural Sciences from the University of Cambridge and my doctorate was from the University of Oxford, researching vortices in the atmosphere of Jupiter, such as the Great Red Spot.

 

 

Research interests

My research interests lie in understanding planetary atmospheres and in the use of that knowledge to aid in the design of spacecraft missions and to interpret the data that is returned. This involves comparative modelling studies of dynamical meteorology and climate processes on different planets.

 

A unique aspect of this work is the assimilation of spacecraft observations of the atmospheres of other planets, a process that combines information from incomplete observations with physical understanding captured by models. This produces a best estimate of the atmospheric state as it evolves with time and helps to identify possible gaps in the models. Primarily I have applied this technique to data from a succession of spacecraft sent to study Mars.

 

I am Co-Principle Investigator for AMELIA entry, descent and landing science on ESA ExoMars 2016 Schiaparelli and Co-Investigator on NOMAD aboard ESA ExoMars Trace Gas Orbiter and on Mars Climate Sounder aboard NASA Mars Reconnaissance Orbiter. My work has included making forecasts for the NASA Mars Curiosity landing in 2012. I am a lead developer of the ESA Mars Climate Database.

 

Although my research focuses mainly on the atmosphere of Mars at present, I have developed and supervised projects that used a Venus atmosphere model, which is able to reproduce the striking atmospheric super-rotation seen in the cloud decks: the atmosphere of Venus rotates up to sixty times faster than its solid surface.

 

My doctoral research was an idealized modelling study of vortices on Jupiter, a Giant Planet, and I have a continued interest in both numerical modelling and laboratory fluid dynamics studies of the processes that lead to the formation of atmospheric zonal jets and vortices within them. This has included simulations of giant extra-solar planets, including those close to their parent stars, known as ‘hot jupiters’.

 

I have also worked on problems involving the Earth's paleoclimate and climate change in the deep past, such as attempts to model neoproterozoic (from around 750 million years BP) frozen ‘Snowball Earth’ states in a coupled atmosphere-ocean climate model.

 

Teaching interests

Since joining the Open University I have written, taught and chaired science modules at all levels of the curriculum. I have worked as a tutor at residential schools at all three levels and helped to develop materials for the online module Practical Science. Most modules I have worked on have been in the area of physics and astronomy, from Understanding the Weather to Electromagnetism, but I have recently worked on the main level 1 Exploring Science module and the level 2 Environmental Science module.

 

I have supervised about twenty postgraduate students on a variety of projects at the OU and Oxford.

 

Impact and engagement

Results from my work have been used by both ESA and NASA in planning space missions. My work for ESA involves working with a variety of industrial users who need access to the data that I provide. I also work on an EU project with a large component of public engagement.

I enjoy science outreach and have acted as nominated academic consultant on OU BBC series, including ‘Wild Weather’ on BBC1.

Surface Pressure Predictions for Candidate Landing Sites of the Mars 2020 Rover

RoleStart dateEnd dateFunding source
Lead01/Mar/201628/Feb/2018NASA (National Aeronautics and Space Administration)
We will provide predictions of surface pressure for all landing sites under consideration for the NASA Mars 2020 Rover. Surface pressure will be derived using a global circulation model with data assimilation (using atmospheric thermal and opacity data from Mars Global Surveyor/Thermal Emission Spectrometer and Mars Reconnaissance Orbiter/Mars Climate Sounder), with an additional constraint from Viking Lander pressure measurements. We will validate the results through comparisons with independent measurements of surface pressure, primarily derived from radio occultations but also using Mars Science Laboratory/Rover Environmental Monitoring Station. We performed the same task previously in support of Mars Science Laboratory entry, descent and landing in Gale Crater, where our predictions achieved an accuracy of ~1%.

Co-investigator01/Apr/201431/Mar/2017STFC (Science & Technology Facilities Council)
The aim of our programme in Astronomy & Planetary Science at the Open University (APSOU) is to carryout detailed investigations of the origin and evolution of galaxies, stars and planets with a special emphasis on our own Solar System through a combination of observation, simulation, laboratory analysis and theoretical modelling. Our research is divided into two broad areas, reflecting the historical research strengths. This research programme is well-matched to both nationally- and internationally-agreed research imperatives. In its final report, A Science Vision for European Astronomy2, Astronet’s Science Working Group identified four broad areas of strategic importance; our research covers major topics within each of these areas. APSOU projects also map onto two of the four Science Challenges that form STFC’s Road Map3 for science (‘How did the universe begin and how is it evolving?’ and ‘How do stars and planetary systems develop and is life unique to our planet?’). The present APSOU programme comprises 20 projects (labelled A to T), of which 6 are for consideration by the Astronomy Observation (AO) panel, 1 for Astronomy Theory (AT), and 13 for the Planetary Studies (PL) panel. The AO projects cover the breadth of the 7 themes recognised as UK strengths in the report of STFC’s Astronomy Advisory Panel (AAP), whilst the 13 PL projects are directed towards answering questions raised in two of the three themes identified as UK strengths in the roadmap of STFC’s Solar System Advisory Panel (SSAP)4.
