Tim Weyrich

Short Bio

I am a Senior Lecturer (Associate Professor) in the Virtual Environments and Computer Graphics group in the Department of Computer Science, University College London, and co-founder and Associate Director of the UCL Centre for Digital Humanities. 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 are appearance modelling and fabrication, point-based graphics, 3D reconstruction, cultural heritage acquisition and digital humanities.
