I am a postdoc working with Danupon Nanongkai at KTH Royal Institute of Technology, Sweden. I finished my PhD in August 2014 at the University of Hong Kong under the supervision of Hubert Chan, with whom I worked as a postdoc from September 2014 to July 2015. I received my BEng degree from University of Science and Technology of China (USTC) in 2010.
