About me

My life-long fascination with the natural world and how we interact with it led me to undertake a degree in Geography at the University of Southampton. Enjoying the sciences and the arts in equal measure, the flexibility of the course enabled me to indulge in a variety of disciplines from philosophy to oceanography. I was fortunate enough to have opportunities to study the impacts of tourism on short-finned pilot whales in the Canary Islands and the behaviour of scarlet macaws in the Amazon. Being close to and observing these spectacular animals in their natural environment, and also seeing firsthand their homes under threat, had a profound impact on me, and I knew from there on that I wanted to work in conservation. The ethos of WWT really aligns with me – the conservation of wetlands, helping people to live sustainably alongside them and benefit from all those life-giving services that they offer, and inspiring people to connect with the natural world. It goes without saying that working in a beautiful wetland and among amazingly talented colleagues does wonders for the motivation!


I undertake ecosystem health work to understand and address threats to wild populations of wetland species and their habitats in the UK and overseas. Most recently, this has involved surveillance activities, research, advocacy and policy work for threats affecting populations of conservation concern, such as lead poisoning and illegal hunting. I engage with a range of stakeholders to bridge research, policy and public platforms and use social research to understand the human dimension of conservation issues in efforts to identify solutions for conservation conflicts. My work involves undertaking data analyses for publication in scientific peer-reviewed journals and writing reports, popular articles and guidance documents for many different audiences. Since 2004, I have been responsible for WWT’s long-term study of the Bewick’s swans at Slimbridge and actively promote WWT's conservation work in national and international media. I have been fortunate enough to have participated in and organised numerous international field work expeditions to study migratory swans in arctic Russia and Iceland. In 2016, I helped to support and co-ordinate more than 40 conservation activities across 11 countries for Flight of the Swans.

I am currently undertaking a part-time PhD with the University of Exeter and WWT entitled “Lead poisoning and illegal hunting of migratory waterbirds: from biological effects to conservation conflict”.


  • Data analysis using methods from the social sciences and ecology to identify, understand and design solutions for issues affecting wetland wildlife. Proficient in R and other statistical packages.
  • Project management from project conception to completion, including design, planning, implementation, budget management, risk management, contractual agreements and reporting.
  • Data collection and management involving survey work in remote and demanding locations and managing long-term datasets.
  • Behavioural observations of wild birds and mammals.
  • Stakeholder engagement and participatory techniques.
  • Communication to a variety of audiences (academics, policy makers, communities and the general public). Previous platforms include the Royal Geographic Society, the European Parliament, the Council of Europe, the Arctic Biodiversity Congress and community group meetings.
  • Media trained and frequent interviewee - I’m always happy to shout about our work! Previous interviews include Radio 4’s Today Programme and Saturday Live, BBC Breakfast and BBC Autumnwatch.
