I'm a 4th year PhD student (2013 - ) in Brown University working with Prof. Erik Sudderth. My research interests are computer vision with applications in 3D scene understanding and computer graphics with applications in image manipulation. I did my undergrad in mathematics at Zhejiang University.

I had joyful internship experiences with Prof. Greg Shakhnarovich (TTIC, 2012 summer), Prof. Huai-Yu Wu (NLPR, 2013 spring), Dr. Sing Bing Kang, Dr. Johannes Kopf (Microsoft Research IVM group, 2015 summer), Dr. Deqing Sun and Dr. Jan Kautz (NVIDIA Research MVC group, 2016 summer). I also had great joy working with Prof. James Hays during my first year in Brown.

  • 2017.6.26: We put our semantic scene flow estimation work online In arXiv:1707.08313.
  • 2017.6.5: I'm working at NVIDIA (at Santa Clara, CA) as a research intern in the summer. Afterwards, I'll spend a year visiting UC-Irvine following my advisor's move.
