The views of experts working in close interaction with policymaking and the public sphere have been extensively studied. Hoppe, for instance, described the views of scientific experts as boundary workers, and discerned several ways of looking at the science-policy boundary (Hoppe 2009 ). Huitema and Turnhout (2009) focus on the institutional level and describe the 'political' roles of experts working in a Dutch boundary organisation. Claire Waterton (2005) also focused on the science-politics boundary, in particular in the field of research policy and funding. Together with Sarah Davies (2008) , who describes the views held by scientists regarding the science-public boundary, these authors analyse the outlooks of individual scientists working across the boundaries of their organisations and disciplines. One of the challenges of discussing the views of scientists in the science-policy and science-public zones is to point out how each of the experts acted in these boundary zones and how they negotiated tensions within these zones, creating an identity for themselves in the process.
