I am a DPhil student in the Department of Biology and Geography, studying Biodiversity Net Gain (BNG) and other methods for ecological compensation, and how they account for real world biodiversity. My DPhil project uses a range of scientific methods (pitfall trapping, emergence trapping, DNA metabarcoding) to address important policy questions, and hopefully prompt changes to how we address impacts on biodiversity.
