Computer Architecture and Systems Research (CASR) Lab

Computer Architecture and Systems Research (CASR) is a research group at University of Central Florida. Our CASR lab works in the areas of computer architecture, systems and security. As computing is becoming increasingly ubiquitous and specialized, ensuring secure and high-performance design for computing systems is imperative. Our group aims to build secure-by-design, efficient, and advanced future systems through novel techniques spanning hardware, computer architecture and systems.
