I am a PhD student working with Prof. Marc Alexa in the Computer Graphics Group at the Technische Universität Berlin. I have a M.Eng. degree from Shanghai Jiao Tong University and a M.Sc. degree in computer science from Technische Universität Berlin.
My research is broadly concerned with human perception and its applications in computer graphics. I have worked on projects studying vergence eye movements in 3D space, using mental imagery paradigm to study encoded visual content in (episodic) memory and measuring where humans look on real three-dimensional stimuli. The central character of my research is eye tracker and I am interested in exploring information revealed by the eyes.

Personal
I was born and grew up in a small city (with only a bit more than 1 million people) in China. Five years of my life is spent in Shanghai for study and I am currently trying to get my PhD in Berlin (and experience its full spectrum of ups and downs). I enjoy travelling as well as the short one-year experience of travel guide in Shanghai. Not long ago I picked up the camera again and try to capture some moments so that something remains in the memory. I enjoy playing guitar and have been in a rock band during my studies in Shanghai. Since 2014 I started playing jazz, and discovered the powerful secret of playing jazz -- no matter how it sounds, you can always entitle it as improvisation. My favorite jazz guitarists are Pat Metheny and Bill Frisell (their music can easily give me goosebumps). The rest of time is spent cooking, learning to play drum-sets, cycling and I also started learning tap dancing (a perfect combination of jazz and rhythm ;)).
