Background Ladislav Kavan, PhD, is a founding member of Stream Studios at The Children's Hospital of Philadelphia. He is an assistant professor with the Department of Computer and Information Science at the University of Pennsylvania. 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 include geometry processing and physically-based simulation, e.g., how to combine data-driven and physics-based techniques. Ladislav has also 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 processing in medicine, anatomically-based modeling and simulation of the human body. Titles and Academic Titles Medical Illustrator Departments and Services Stream Studios Medical Illustration Patient Experience Ratings About the Patient Experience Rating System The Patient Experience Rating is an average of all responses to the care provider related questions shown below from our nationally-recognized Press Ganey Patient Satisfaction Survey. Patients that are treated in outpatient or hospital environments may receive different surveys, and the volume of responses will vary by question. Responses are measured on a scale of 1 to 5 with 5 being the best score. The comments are submitted by patients and families and reflect their views and opinions. The comments are not endorsed by and do not reflect the views of Children’s Hospital of Philadelphia.
