I am a Ph.D. candidate in computer science at Duke University. My current research focuses on the interface of computer science and DNA nanotechnology. Specifically, I develop DNA nano-devices that perform computation for useful applications such as cancer detection, immune response activation and targeted therapy. Before my Ph.D. study, I received my M.Sc. degree in computer science from Duke University in 2012, and my B.E. degree in computer science and technology from Wuhan University in 2010.
