Usman Tariq is an associate professor with the college of computer engineering and sciences at PSAU. He holds a Ph.D. from the Ajou University, South Korea and led the design of a global data infrastructure simulator modeling, to evaluate the impact of competing architectures on the performance, availability, and reliability of the system for Industrial IoT infrastructure. His international collaborations/collaborators include but not limited to: NYIT, Ajou University, PSU, University of Sherbrooke, COMSATS, NUST, UET, National Security Research Institute (NSR), Embry-Riddle Aeronautical University, Korea University, Manchester Metropolitan University, University of Bremen and Virginia Commonwealth University.

Currently he is interested in applied cyber security, advanced topics in Internet of Things, and health informatics. His research focus is on the theory of large complex networks, which includes network algorithms, stochastic networks, network information theory, and large-scale statistical inference. As a network security theorist, his contributions towards addressing these challenges involve designing better wireless access networks and processing social data and scalable algorithms that can operate in data center like facility.
