Stephen Butterfill and Diarmuid Costello have both been appointed Professors in Philosophy.

Professor Butterfill's research has focused on philosophical issues in the areas of cognitive and developmental psychology but current projects include research related to joint action and mind reading. He is also at present involved with a number of theoretical and experimental collaborations with scientific colleagues.

Professor Costello's research involves both analytic and continental approaches to aesthetics and the philosophy of art, informed by recent debates in art history and theory. His book 'On Photography: A Philosophical Inquiry' (London, Routledge), was published in October 2017.
