I am an assistant professor in the Computer Science Department at University of Virginia. Earlier, I was a postdoctoral researcher at Northeastern University, advised by Professor Daniel Wichs. I got my Ph.D. in Computer Science at Cornell and then worked as a postdoc at CMU, both advised by Professor Elaine Shi. Prior to that, I got my B.S. and M.S. degrees from National Taiwan University, and then I was a software engineer.
