Data visualisation

From 2004—2016 I worked at the intersection of computer science and visual design. I investigated, designed, and implemented interactive visualisation methods to support analysis of and insight into abstract data.

My work included the following. As a Leverhulme Fellow at the School of Computing, University of Leeds, I developed visualisation methods for cell biology data sets. This involved close collaboration with the Errington Lab at Cardiff University. In earlier work, I developed visual parameter optimisation methods with the Carpenter Lab at the Broad Institute of Harvard and MIT, and techniques to visually support systems analysis with engineers at Eindhoven University of Technology.

I was a programme committee member of international conferences including EuroVis (the EG/VGTC Conference on Visualisation) and BioVis (the Symposium on Biological Data Visualization). I also published a number of research articles on data visualisation (a selection is listed below). I hold a PhD from Eindhoven University of Technology, the Netherlands.
