Prior to that she served as faculty at Saint Louis University in Missouri, and at the University of Dublin, Trinity College, Ireland. Her BSc in Computer Science, and PhD in Computer Graphics were granted by the University of Bristol (UK) in 1996 and 2000 respectively. Her research focuses on the advancement of computer graphics and scientific visualization through novel approaches for optimizing an individual's experience when creating, viewing and interacting with virtual spaces. She investigates new ways to exploit knowledge of human visual perception to produce high quality computer graphics and animations more efficiently. Her most recent work in Subtle Gaze Direction investigates techniques to guide a viewers gaze about an image, without the viewer being aware that their gaze is being directed.
