My primary research focus is ecocriticism, or environmental literary and cultural criticism, and I also have significant publications in human-animal studies (HAS) and eco-pedagogy. I am the author of Ecocriticism (Routledge 2004; 2011 2nd edn.; 2023 3rd edn.), the definitive student introduction, and lead co-author of 'Climate Change Scepticism: A Transnational Ecocritical Analysis' (Bloomsbury Academic 2019). In recent years, I have become interested in questions of academic freedom and freedom of speech, whilst my research has become increasingly multidisciplinary.
