Personal details

  • BA Hons Physics (Oxford, 1985) , PhD (Oxford, 1991)

I am the Head of the Earth Observation Science group at The University of Leicester and the Director of the National Centre for Earth Observation (from 1 October 2014).

I received my D.Phil. from Oxford University in 1991 for studies of infrared laboratory spectroscopy and remote sounding of the atmosphere. I have particular experience in satellite data for atmospheric composition and surface temperatures, infrared radiative transfer, mission concepts and inversion techniques such as optimal estimation.

I am a visiting Fellow of the Department of Physics in Oxford (Sub-department of Atmospheric, Oceanic and Planetary Physics).

I am Chair of the UK Space Agency Earth Observation Advisory Committee, Chair of the Defra UK Copernicus Atmosphere Networking Group and a member of the NERC Pool of Chairs.

I play major roles to several satellite missions including Science Manager and Leader of the Principal Investigator team for the ATSRs as well as participating in the ATSR Quality Working Group.

I am also a member of the MIPAS Quality Working Group and am a member of the GERB International Science Team. Other missions that I lead with my team work on include instruments on Metop such as IASI and AVHRR.

I am a former member of the European Space Agency Earth Sciences Advisory Committee and Future Technology Panels. I have worked with the Centre for Earth Observation Instrumentation (CEOI), including challenge reports for the UK, the multi-University CEOI training programme, and also CEOI projects.

Entrepreneurship and Impact Positions

As Co-Director of G-STEP, I am involved in the promotion of Earth Observation data for use by East Midlands, national and international businesses.

I am also a member of the Space Innovation and Growth Strategy (IGS) Implementation Team and a former member of the Space IGS Steering Broad which delivered the Space Growth Action Plan. I played a leading role in the implementation of the academic-industrial.

Science communication

Several of my PDRAs and I have worked with the Space Academy to develop the Blue Marble, primary school EO outreach programme. We also developed masterclasses for Space Academy. Our work for primary schools was published in Muller, 2013.

I am also School Director for the FORMAT-EO training school for undergraduates from eight European institutions, funded by the Erasmus IP programme and Lecturer on the ESA EO Summer School 2014.

My team and I work on a wide range of research projects, utilising Earth Observation for climate and environmental science, including direct observations of change and model evaluation and improvement. Projects linking surface change with atmospheric composition are currently a major interest.

I am currently involved in several major projects including GlobTemperature a new ESA initiative focussed on developing new satellite data sets and improving the uptake of global-scale satellite land surface temperature by the broad research and operational user communities. I am a Principal Investigator of ATSR and part of the Validation Team. Other projects that I am connected to include E-Stress, the EarthTemp network and humidity and carbon monoxide retrievals from IASI.
