Biography
Professor Turner has been awarded 30 patents for his work on switching systems and has many widely-cited publications. In 2007, he was elected to membership in the National Academy of Engineering. He is a fellow of the Association for Computing Machinery (ACM) as well as the Institute of Electrical and Electronics Engineers (IEEE). In 1994, he was awarded the IEEE Koji Kobayashi Computers and Communications Award, and in 2000, the IEEE Millennium Medal. Washington University has awarded him two of its highest honors: the Founder's Day Distinguished Faculty Award, and the Arthur Holly Compton Faculty Achievement Award. Professor Turner also won an Engineering Alumni Achievement Award in 2007.
Research
As a professor at Washington University in St. Louis (WUSTL), Professor Turner established the Advanced Networks Group and developed ideas for multicast switching that were demonstrated in experimental systems and then transferred to commercial practice through license agreements with industry. His pivotal 1986 paper, "New Directions in Communications," foresaw the convergence of data, video and voice traffic and showed how scalable switch architectures could enable this convergence. In 2002, the paper was reprinted as a "landmark article" in the 50th anniversary issue of IEEE Communications Magazine.

In 1988, Professor Turner teamed with WUSTL colleagues Jerry Cox and Guru Parulkar to found the Washington University Applied Research Laboratory, which he currently directs. Their research led to the development of a series of high performance networking systems and technologies, including an early metropolitan area testbed using Asynchronous Transfer Mode switches that Turner designed. Continuing their collaboration, Turner, Cox and Parulkar founded the start-up company Growth Networks, which developed high performance switching components for Internet routers, and was acquired by Cisco Systems in 2000.

In recent years, Professor Turner's research has centered on how to enable new network services by making Internet routers more readily extensible. The focus of his current work is on high performance platforms for overlay hosting services, a new class of systems that make it dramatically easier to deploy innovative new network services and the applications that use them.

Selected Research
Design of Performance Engineered Overlay Networks: The objective of this project is to enable overlay networks that have the performance and scaling characteristics needed to deliver advanced network services in the internet. The project centers on a specific overlay network, designed to enable very large-scale virtual worlds that can support high quality person-to-person interaction in support of group collaboration.
