About
Overview
I am a Lecturer in City's Computer Science Department and a member of the giCentre. My research interests are in Data Visualisation, Visual Analytics and Human Computer Interaction. I supervise both PhD and MSc students (more under the Research tab).
I currently coordinate City's Programming Bootcamp and teach Java Programming to imcoming Stage 1 students. In the past I've taught modules on Data Visualisation, Human Factors in Computing, Human Computer Interaction, and Functional Programming.
I am also the Computer Science Department's Progression and Support Director and a member of its ExCo. In the past I've been a Senior Tutor for Research and coordinated the periodic review of our department's doctoral program.

Research
My research is focused on Visualisation, Visual Analytics, and Human Computer Interaction. I typically pursue interdisciplinary collaborations with research colleagues from other domains (e.g., biology, food policy) and industry partners (e.g., energy decarbonisation) to understand how they use data to advance knowledge and make decisions. I then create interactive data visualisations that can help them do this more effectively. In the process, I try to develop novel, generalisable data visualisation techniques as well as understand the general principles that govern how people interact with and make sense of data shown visually. To do so, I design and prototype data visualisation solutions; come up with new techniques that blend computation and interaction; and conduct user research and evaluation in various forms (e.g., eye-tracking, controlled user studies, contextual inquiry).
I publish regularly in high-impact visualisation and Human Computer Interaction venues (h-index = 22). Over the years I have co-authored around 40 publications, 20 of which in IEEE VIS, EuroVis, Transactions in Visualization and Computer Graphics (TVCG), Conference on Human Factors in Computing (CHI), and Nature Immunology. Several were awarded 'best paper' awards. I also review regularly and am a member of program committees for IEEE VIS, EuroVis, the Symposium of Eye Tracking Research & Applications.
