I focus primarily on how biodiversity offset markets can be designed to assist conservation management in the UK, as well as valuation of ecosystem goods and services in the coastal and marine context. My research draws on a range of disciplines including ecology and economics to: 1. Understand the key design principles of biodiversity offset markets to ensure that ecological goals are met at the least cost to society; 2. Investigate the impacts of biodiversity offsets on changing land use in the context of the UK 25 Year Environment Plan; 3. Provide evidence on the socio-economic value of deep sea ecosystem goods and services in the context of the EU Blue Growth Agenda; 4. Advance literature on the appropriateness of stated preference methods to value the environment.
