Profile

Since 2015 I am professor for Computer Graphics and Interactive Systems at the Berlin University of Applied Sciences and Technology in Berlin. I graduated from TU Berlin in 2013 and hold a diploma from the Computer Science and Media program at Bauhaus University Weimar. During my studies I attended the University of British Columbia in Vancouver and the Max Planck Institute for Computer Science in Saarbrücken. From 2006-2008 I worked as a software developer at ART+COM Studios in Berlin, where I was involved in the development of several innovative media installations. From August to October 2012, I was a visiting researcher at Disney Research Zurich. Between 2014 and 2015, I worked as a Principal Research Engineer at a machine learning startup. I am also co-founder of the art technology platform kunstmatrix. My research interests include computer graphics, computer vision, machine learning and digital fabrication. I am the head of the Intelligent Interactive Systems group.
