Hossein Sayadi

Founder & Director

Intelligent, Secure, and Energy-Efficient Computer Systems (ISEC) Lab, in the Department of Computer Engineering and Computer Science of the California State University, Long Beach under the direction of Dr. Hossein Sayadi, is a research group for exploring different challenges associated with Intelligent, Secure, Energy-Efficient Computer Systems and Architecture Design. ISEC Lab has broad research interests in Hardware Security, Computer Systems Cybersecurity, Computer Architecture, Applied Machine Learning, Energy-Efficient Computing, and Heterogeneous Multicore Processor architectures design and optimization. The overarching research vision of ISEC Lab is to architect the modern computer systems more efficiently for Secure and Sustainable Computing in presence of security and energy-efficiency challenges. In particular, the current research theme of ISEC Lab concentrates on hardware & architecture security, run-time malware detection, processor architecture side-channel attacks analysis, adversarial machine learning, and scheduling and resource management in heterogeneous multicore architectures. In our research, we are mainly interested in proposing novel solutions to address major challenges of security and energy-efficiency of modern computing systems that the computer design industries are currently dealing with, across various emerging application domains including High-Performance Computing, Embedded Systems, Internet of Things (IoT), and Cloud Computing.
