My research focuses on applying theoretical results from stochastic processes and queueing theory to the quantitative study of hardware and software architectures. Dr. Ould-Khaoua’s current research interests are performance modelling and evaluation of computer networks, wireless networks, and parallel machines, distributed and cluster computing systems.
