Research Activities
My research interests can be generalized to the field of Computer Architecture and Systems.
My current research deals with hardware–software mechanisms for concurrency, resiliency, and security of future parallel computer architectures.
I enjoy simulating and building architecture prototypes.
Hardware Concurrency in Parallel Computer Architectures
Many emerging applications comprise real-time automated processing, interpretation, and intelligent decisions using large volumes of input data, while simultaneously decreasing the time necessary to arrive at a decision. The objective of this research is to explore both hardware and software concurrency challenges holistically, characterize key bottlenecks, and explore architectural methods that improve performance, lower energy, and lower programmer effort.

Secure Parallel Architectures
Computer systems have recently seen a rise of malicious exploits on processor hardware. Virtualization technologies expose hardware resources, thus requiring strong isolation and obfuscation guarantees for security. This research aims to address this challenge by devising methods to secure parallel processors, while meeting the efficiency and responsiveness expectations of the system.
Resilient Parallel Architectures
The focus of this reseaerch is to build architectural mechanisms and protocols that exploit application through hardware layers to co-optimize processor resiliency and efficiency.
