Research projects

My current research interests are in security (with a focus on consumer computing) operating systems for multi-core architectures, networking,  and sensor networking.

My research, since 1993 has been in collaboration with the parallel and distributed systems group at New York University (Z. M. Kedem and V. Karamcheti). The research topics include Security, Networking and Operating Systems. I have also collaborated with Dr. Nong Ye of Industrial Engineering, ASU.

My funding sources have been SFAz, NSF, AFOSR, DARPA and Microsoft.
