Associated Faculty in Computer Science

My research interests lie in the areas of computer architecture, computer security and multimedia architecture. My current research focuses on trustworthy computer architecture and multi-core security for facilitating secure and resilient systems. I investigate hardware-enhanced security for secure cloud computing, secure virtualization and mobile security. I also study how to design more trustworthy hardware subsystems with the goal of improving security and performance simultaneously. This includes, for example, secure cache architectures that do not leak information through software cache-based side-channels, while improving overall cache performance.

My work includes minimal software-hardware Trusted Computing Bases, hardware trust anchors, mitigating processor-induced covert and side channels, wireless security and security validation. I am also investigating self-protecting data, no-overhead cryptography, bio-inspired defenses, and the mitigation of Internet and wireless epidemics. While I investigate clean-slate architecture to show the possibilities for future systems, I also investigate architectures with minimal changes to the computing ecosystem for faster deployment, based on my extensive industrial experience in the design of computer products, microprocessors and instruction-set architecture.

My research also involves the design of high-performance microprocessors, including very fast permutation and advanced bit manipulation instructions useful for cryptography, multimedia and communications. In the manycore processor chip era, I am also interested in new models for ubiquitous parallelism that are inherently secure and trustworthy.
