About Me:

I am a Senior Assistant Professor at Università della Svizzera italiana (USI) in Switzerland where I am heading a group on Perception, Display, and Fabrication. In my research, I combine perception, computation, and hardware to create better display and fabrication techniques. More specifically, my interests include human perception, new display technologies, image/video processing, 3D printing, and computational fabrication. Before my current position, I was an Independent Research Group Leader at Saarland University, MMCI and Max Planck Institute for Informatics in Germany. I have also spent two years as a postdoc with Prof. Wojciech Matusik at MIT. I obtained my Ph.D. from Saarland University and Max Planck Institute under Prof. Karol Myszkowski and M.Sc. degree from University of Wrocław in Poland. I usually spend my free time with my family as well as enjoy various outdoor activities such as mountain biking, hiking, running, skiing, and mountaineering. I also love taking photographs although for this I have recently slightly less time.
