Personal Details

I joined the University of Leicester in 2014 after many years working in the commercial geospatial services industry, and have, in total, 20 years’ experience working in the UK space sector. I previously worked for BAE SYSTEMS and Airbus. More recently I was a NERC Knowledge Exchange fellow helping support academic-industrial collaborations in the field of Earth Observation data.
I have a PhD in “High resolution polarimetric imaging of biophysical objects using synthetic aperture radar” from the University of Sheffield (available at http://etheses.whiterose.ac.uk/10223/)

Research

My research is focused around the use of remotely sensed Earth Observation data for applications related to the land environment, particularly land cover/land use and agriculture. Mostly this uses satellite imagery, but I also make use of aerial photography and UAV data where needed. In particular, I am interested in;

  • Land cover/land use change mapping, especially with respect to long term multi-decadal change.
  • Agricultural applications of remote sensing including climatic impacts, livestock behaviour, soil moisture and the impact of flooding on agriculture.
  • Agent based modelling of the natural environment.
  • Methods for establishing user requirements for remote sensing based services.
  • Interactions and scattering mechanisms between incident radar signals and natural targets on the Earth’s surface.
