I am fascinated by the politics that emerge when attempts are made to govern environmental problems using the tools and methods of public policy. I have examined how these different forms of politics have played out in relation to different aspects of governing including the use of new policy instruments, policy coordination across sectors, policy innovation and policy dismantling. I undertake comparative work on these topics in substantive policy areas such as climate change and sustainable development. I am particularly interested in governing processes that occur in the European Union, its Member States and third countries outside of Europe. I have published many papers and books on these themes, including Dismantling Public Policy (Oxford University Press, 2012), The Tools of Policy Formulation (Edward Elgar, 2015, with John Turnpenny) and the third edition of EU Environmental Policy (Earthscan, 2012, with Camilla Adelle). Between 2014 and 2018 I was the Chair of COST Action IS1309 (Innovations in Climate Governance - INOGOV, 2014-8), a 28 country network of excellence.
