Katrina has interests in 19th and 20th European thought, including the work of Nietzsche, Freud, Foucault and Ricoeur. She is particularly interested in thinkers who explore problems and possibilities concerning how we understand, know and can work on and transform the self. Her publications to date have explored how various techniques or technologies of the self in the work of Nietzsche, Freud and Foucault address problems of the self, at the same time as addressing interpretative issues concerning their work. She has also published on the philosophy of photography and film and is currently exploring how art works can serve as technologies of the self. She is working on a new book project Visual Art and Projects of the Self, which will be published with Edinburgh University Press.
