Dr. Hui Zhang

Co-Founder, Chief Scientist, Chairman of the Board

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.
