I am a research scientist in the Ads Core ML Eng team at Facebook.
I completed my Ph.D. in computer science at Harvard University, where I was fortunate to have professor Salil Vadhan as my advisor. Before that, I studied physics at the National Taiwan University and computer science at the Columbia University.
Research intern at Facebook, Summer 2018
Teaching fellow of CS225 Pseudorandomness, Fall 2016
Teaching fellow of CS124 Algorithm, Spring 2017
Software engineer intern at Rocket Fuel Inc, Spring 2014
My research interests include pseudorandomness and theory in differential privacy. During the visiting at Academia Sinica of Taiwan in 2015-2016, I was hosted by Kai-Min Chung, who lead me into the world of quantum information.
