Research at NCL

At NCL, we focus on developing dependable, scalable, and sustainable Cyber-Physical System (CPS). Broadly speaking, CPS is an informed integration of computing system and the environment within which the system operates. Our angles of investigation in CPS include real-time systems, fault-tolerant systems, and Internet-of-Things (IoT).
