I passed my PhD defense in July 2016. I have worked with Professor Emmett Witchel on operating systems and security. I also collaborate with Professor Vitaly Shmatikov. I received my Bachelor's degree from Shanghai Jiao Tong University in 2011. I previously worked at Facebook, Microsoft Research and Google for summer internships.
