I am a post-doctoral research fellow at Poly. I obtained my PhD from National University of Singapore in 2006.

My research interests include cryptography as well as multimedia, biometric, and network security. My current research focuses on the security of handling noisy data, such as images and biometrics. I am interested in the design and application of cryptographic schemes to deal with security threats where noisy data are used, and I emphasize rigorous treatment and provable security. I'm working on serval projects at the moment: the first looks at the security issues involved in handling noisy data (for example, biometric authentication and digital watermarking schemes), and the second examines security in authentication data integrity in networking (more specifically, issues related to content distribution with network coding and key predistribution schemes and their applications in digital rights managements). I have had my research published in various places, among them EUROCRYPT, ASIACRYPT, INFOCOM, and ICNP.

I've been interested in computer security since my undergraduate years, and the more I found out about it, the more I was attracted to the beauty of the mathematics behind it, and to the ingenious thinking of the great people in this area. It is always like a game to me: attacking and defending a real system, or a mental game between good guys and bad guys. It is always fun. Besides working on security problems, I also love reading, sports, movies, and music. I especially like kung-fu movies (Bruce, Jet, Jackie, and more), and kung-fu novels (in Chinese).

The main reason I chose Poly is that there is a very strong security group here, where people study all kinds of interesting problems in various areas. I really like talking to people with a wide array of different backgrounds who are working on a range of different problems. This often gives me a lot of inspiration. In general, I've found Poly a good place to be, and one of the advantages of being in New York is that there are a number of top universities nearby, and a lot of conferences and workshops taking place in the area. This makes communication and discussion with other researchers much easier. I would say that half of my ideas are the direct results of discussions with others.

My long-term goal is to continue to do research in computer security and to stay in academia, because thinking about interesting problems and finding ways to solve them is really fun for me.
