I am currently pursuing a Ph. D. at the Johns Hopkins University Information Security Institute.  My research includes techniques for privacy-enhanced information storage, radio-frequency identification (RFID), and elliptic curve cryptography.  From 1999-2003, I served as a senior technical staff member at AT&T Laboratories/Research in Florham Park, NJ, working on a variety of projects including audio coding/secure content distribution, streaming video and wireless localization services.  My advisors are Avi Rubin and Susan Hohenberger.
