Jessica J Williams

Postdoctoral research fellow, UCL

I am a conservation biologist working on the SHEFS project within the Centre for Biodiversity and Environment Research at UCL. Currently, I am investigating the impacts of land-use change and climate change on biodiversity within South African agricultural areas, and the resilience of nature's benefits to people under such changes. Further to this, I am a STEM Ambassador and thoroughly enjoy organising and getting involved with outreach activities.
