I am a postdoctoral research associate working at Maryland Cybersecurity Center, University of Maryland. My hosts are Professors Jonathan Katz, Elaine Shi and Dana Dachman-Soled. Before joining UMD, I received my PhD degree from Brown University under the supervision of Professor Anna Lysyanskaya. I received my bachelor degree from Department of Electrical Enginieering, National Taiwan University.

Here is my cv.

I am interested in information security with focus on cryptography. Particularly I tackle security challenges in various scenarios of cloud computing, and develop new techniques to handle these security issues, such as: how to compute on encrypted data, how to verify computation in outsourced environments, and how to protect memory/computation under physical attacks.
