SIGGRAPH 2011
Dr. Chris Wojtan is an assistant professor at the Institute of Science of Technology Austria (IST Austria), where he is establishing a computer graphics lab with a research focus on physically-based animation, geometric modelling, and numerical techniques. His computer graphics contributions include methods for animating detailed viscoplastic materials, several techniques for controlling physics simulations, and an algorithm for efficiently computing topological changes in deforming triangle meshes. His research into mesh-based fluid surface tracking has helped produce extremely detailed liquid surface animations, allowing arbitrarily thin features and detailed crown splashes. Prior to his work at IST Austria, Chris received his Ph.D. in Computer Science from the Georgia Institute of Technology in 2010, and he worked as a visiting scientist at Carnegie Mellon University and ETH Zurich.
