Prior to coming to UCL, I was a Postdoctoral Teaching Fellow of Princeton University, working in the Princeton Computer Graphics Group, a post I took after having received my PhD from ETH Zurich, Switzerland, in 2006. My research interests include content creation, computational photography, appearance modelling and fabrication, point-based graphics, cultural heritage analysis and digital humanities. I am currently deputy director of the UCL Centre for Digital Humanities; member of the executive committee of Eurographics; member of the steering boards of the Eurographics Workshop on Graphics and Cultural Heritage and of the UCL Centre for Digital Humanities; steering committee EPSRC Doctoral Training Centre of Science and Engineering in Arts, Heritage and Archaeology (SEAHA). I serve as Associate Editor for IEEE Transactions of Visualization and Computer Graphics (TVCG) and am a member of the Association for Historical and Fine Art Photography (AHFAP), special interest group Libraries & Archives Imaging; member of EPSRC College, BCS, ACM SIGGRAPH, Eurographics and of Gesellschaft für Informatik. I lead the REF2021 team of UCL Computer Science. Past roles include coordinator of the Innovate Training Network (ITN) DISTRO; programme director MSc ICT Innovation; University contact within EIT Digital and co-designer of the EIT Digital Master and Doctorate Schools; Associate Editor of Computer Graphics Forum and of Elsevier Computer & Graphics; member of UCL's Athena SWAN Committee Computer Science; departmental Study Abroad and Affiliate Tutor.
