Background  

Dan

I am an inter-disciplinary Conservation Scientist interested in wildlife trade and use, its sustainability, governance, and economics, including human behaviour, and pangolins and their conservation.

I joined ICCS in April 2018 as a Postdoctoral Researcher on the Oxford Martin School Programme on the Illegal Wildlife Trade project, ‘Exploring the effective use of celebrities in wildlife demand reduction: changing perceptions of pangolins in Vietnam’.

I completed my PhD, ‘Reforming international wildlife trade interventions in CITES’, at DICE, University of Kent, UK in 2014. I subsequently joined IUCN’s Global Species Programme where I led the organisation’s contribution to CITES and broader illegal wildlife trade work, prior to joining the University of Oxford. In 2012, I re-formed the IUCN SSC Pangolin Specialist Group and have since served as Chair of the group.   

 

 

 

 

My research interests include the use and trade of wildlife, its sustainability, governance, and economics, including human behaviour, and pangolins and their conservation.

 

 

My current research forms part of the Oxford Martin School Programme on the Illegal Wildlife Trade, and two projects in particular:

Exploring the effective use of celebrities in wildlife demand reduction: changing perceptions of pangolins in Vietnam

This research involves understanding demand for, and consumption of, pangolin products in Vietnam, principally the meat of the animals and their scales. This will inform implementation of a celebrity associated demand reduction campaign for pangolins in order to evaluate the effectiveness of celebrities as a tool to change consumer behaviour. It also involves examining the feasibility of pangolin farming through the development of bioeconomic models, and investigating online trade in pangolin products.   

Towards effective global wildlife trade policy

This research involves evaluating the extent to which social-ecological factors have been considered in CITES listing decision in the last ~20 years, and developing an evidence-based theory of change to identify the conditions under which amendments to the CITES Appendices would be likely to contribute to improving the status of species. It further involves convening disparate stakeholders to guide policy directions for high-value traded species through participatory scenario planning, with a focus on pangolins and rhinos. This research will inform proposed reforms to decision-making in CITES to ensure that decisions are underpinned by evidence.
