I received my PhD in 2015 from KTH Royal Institute of Technology, where I was extremely fortunate to be advised by Prof. Johan Håstad. I then did a postdoc at EPFL, under the supervision of Prof. Ola Svensson.
I did my undergraduate studies at Shanghai Jiao Tong University. I had also worked as an intern student at Theory Group of Microsoft Research Asia, supervised by Prof. Pinyan Lu.
During the fall semester of 2013, I visited Prof. Ryan O'Donnell at Carnegie Mellon University. I also did a summer internship at Toyota Technological Institute at Chicago with Prof. Madhur Tulsiani June - August, 2014.
