At Bell Labs, Mohcene developed robust design and statistical design methods for optical and wireless telecommunication systems. Mezhoudi extended his work to the planning and design of optical backbone, core, and metropolitan networks. He also developed methods and design techniques for integrating robustness and reliability optical network architecture. Mezhoudi, who is the author of numerous technical publications in his areas of research interest, earned his M.S. and Ph.D. in Electrical Engineering and Electro-Optics from Stevens.
