Professional summary

Research Interests

I am an ecologist and GIS specialist at the UK Centre for Ecology & Hydrology, and a Senior Research Associate at the University of Oxford (Dept. of Biology). My main interests are British farmland and woodland, the Białowieża Forest in Poland, and the ecology of birds and mammals. I undertake field surveys, spatial and statistical analyses, mapping of remote sensing data (e.g. LiDAR, Sentinel, drone), and combine these datasets to understand ecosystems and species distributions. My research includes:

  • Ecology and behaviour of woodland birds, e.g. long-term studies of Marsh Tits, Willow Tits & Wood Warblers.
  • Agri-environmental schemes, hedgerows, farmland birds & small mammals.
  • Rewilding and natural regeneration of woodland.
  • Invasive species, including the Grey Squirrel and Red-billed Leiothrix.
  • Pesticide effects on birds of prey, particularly rodenticides (SGARs).
  • Training of fieldwork methods (bird/mammal trapping & surveying) & GIS for ecology.
