Personal profile
Research overview
I am an Honorary Research Fellow at the University of St Andrews, where I completed my PhD in Computer Science. My research sits at the intersection of Human--Computer Interaction, computer vision, and trustworthy AI, with a focus on gaze estimation, gaze interaction, and eye-movement analysis for interactive systems. I develop robust sensing and interaction methods for mobile and wearable devices, combining technical model development with human-centred evaluation. My long-term goal is to democratise reliable eye tracking in everyday settings and to translate gaze and multimodal behavioural sensing into practical, secure, and socially beneficial digital technologies.
