Prior to joining Penn, he was a senior researcher at ETH Zurich and research scientist at Disney Interactive Studios. Ladislav’s research focuses on real-time graphics and animation. His core area of expertise is deformation modeling, in particular skin deformation for virtual characters, often known as skinning. His other areas of interest geometry processing and physically-based simulation, e.g., how to combine data-driven and physics-based techniques. Ladislav also has experience with quaternions and related algebras (dual quaternions), subspace methods, discrete differential geometry, collision detection and real-time rendering, especially in the context of computer games. Most recently, he is studying applications of real-time graphics and geometry processiong in medicine, anatomically-based modeling and simulation of the human body.
