I am an Associate Professor in Communications and Journalism at the University of New South Wales, Australia. My research interests centre on visual representation, news photography, text-image relations and discursive news values analysis. I am currently exploring the visual representation of diverse characters in Australian children's picture books.
I have published in the area of photojournalism and social semiotics, including two monographs, one with Routledge, Photojournalism Disrupted: The View from Australia (2019), and another with Palgrave Macmillan, Photojournalism: A Social Semiotic Approach (2013). I am also the co-author (with Monika Bednarek, University of Sydney) of two books examining the news media: News Discourse (2012, Continuum), and The Discourse of News Values (2017, Oxford University Press).
I am a former press photographer, having worked for British newspapers in the early 1990s.
I am a past President of the Australian Systemic Functional Linguistics Association (ASFLA) (2018-2021). And I am the current Chair of the Halliday & Hasan Archive Working Group.
