About I am an Associate Professor in Creative Technologies at the School of Computer Science and Statistics at Trinity College Dublin. I am also a Fellow of Trinity College, a Principal Investigator in the ADAPT Research Centre, and a member of the Graphics, Vision, and Visualisation Group. I received my PhD in Computer Graphics in 2006 from TCD. My research interests include computer graphics, character animation, virtual humans, VR, and perception. My main focus is on real-time performance capture and perception of virtual humans.
