My primary research interests are within the field of extrasolar planets. I was responsible for the SuperWASP project in La Palma, which along with its sister facility at SAAO, has become the most successful ground based planet detection experiment, receiving the group achievement award from the Royal Astronomical Society in 2010. I am also a founder member of the Next Generation Transit Survey project: This concentrates the diversity between smaller planets, allowing for greater analysis and comparison between Neptune-like planets and Super-Earths.
Studing small planets around solar type stars is best done from space. There are two ESA missions with this goal. The first is the ESA S mission CHEOPS (launch 2017) is a swiss led satellite designed to followup known transiting planets (eg NGTS or TESS planets) and detect transiting planets amongst the RV detected systems. Further in the future we have ESA M mission PLATO (launch 2024) which is designed specifically to detect and characterise habitable zone rocky planets. I am the science coordinator for PLATO. Transiting planets are the only objects we can measure accurate radii for, and hence density. This is used to compare directly with theoretical models of planet composition. PLATO will be capable of dedtecting planets with moons and rings etc.
My other research interests include Space Sitauation Awareness and specifically Space debris. Originally this interest started as just a use for our observatory but over the last couple years I have become interested in specific problems such as the nature of debris field at geostationary orbit. This material has profound implications for our telecom satellites etc.
I am the recipient of a Royal Society Wolfson Merit Award.
