Dr. Hui Zhang


As Conviva’s Chief Scientist, Co-founder, and Chairman of Board, Hui brings 20 years of pioneering research experience to the design and build of the company’s media control platform. As a professor of computer science at Carnegie Mellon University (CMU), Hui has established himself as one of the world’s leading authorities on Internet Quality of Service (QoS), video streaming, network control, and Internet architecture.

Hui is credited with teaching and mentoring many computer network researchers who are now in industry (Facebook, Google, IBM, Microsoft) and academia (University of California, Berkeley, Rice, Purdue). In particular, he supervised Ion Stoica’s 2001 award-winning Ph.D. dissertation on Internet QoS. In addition, his End System Multicast (ESM) research group at CMU pioneered the overlay multicast architecture and developed the world’s first peer-to-peer live streaming system. His paper on ESM won the ACM SIGMETRICS Test of Time Award in 2012 for its significant impact on research, methodology, application, and transfer in the last decade. His 4D research project advocated the network control architecture that separates control logic from data devices, and was the precursor to the Software Defined Networks (SDN) initiative.

Hui was elected to be a Fellow of ACM in 2006 and received the Alfred Sloan Fellowship in 2000. He received the National Science Foundation Career Award in 1996 and held the Finmeccanica Chair in Computer Science at CMU from 1998 to 2001.

His research has led him to develop techniques and architectures that allow powerful and flexible network services to be deployed on the Internet, without compromising scalability. Furthermore, he has designed algorithms and systems with strong theoretical foundations in the areas of peer-to-peer and cloud computing that can be deployed in the real world.

Ion received the ACM Best Dissertation Award for his Ph.D. thesis “Stateless Core: A Scalable Approach for Quality of Service in the Internet.” This highly coveted accolade is only bestowed on one recipient a year. Ion’s other achievements include the IEEE William R. Bennett Award, the Alfred P. Sloan Fellowship, The Presidential Early Career Award (PECASE), the Okawa Foundation Fellowship, and the 2007 CoNEXT Rising Star Award.
