Holger Winnemöller
Research Scientist

I am a research scientist at Adobe Systems, Inc. I am interested in perceptual aspects of image creation and generation, particularly non-photorealistic graphics. I enjoy combining my fondness of creative expression (drawing, sketching, and design) with the challenges of user-centric applications. I obtained my PhD in Computer Science from Northwestern University in 2006. Previously, I spent several years in South Africa at the University of Cape Town and Rhodes University in Grahamstown, where I received my M.Sc. in Computer Science and my B.Sc. (Hons.) in Computer Science and Physics with Applied Electronics. I am a member of ACM and ACM SIGGRAPH.
