The Executive Team

Dr. Hui Zhang, Co-Founder and Chief Executive Officer

As Conviva’s co-founder and Chief Executive Officer, Dr. Zhang 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), Dr. Zhang has established himself as one of the world’s leading authorities on Internet Quality of Service (QoS), video streaming, network control and Internet architecture.

Dr. Zhang 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.

Dr. Zhang 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. Prior to co-founding Conviva, Dr. Zhang served as chief technology officer of Turin Networks from 2000 to 2003.

Dr. Ion Stoica, Co-Founder and Chief Technology Officer

An accomplished scientist and author, Dr. Ion Stoica is Conviva’s co-founder and chief technology officer. He drives the technical advancement of the Conviva media and control platform.

Before co-founding Conviva in 2006, Dr. Stoica spent over 15 years involved in networking research with an emphasis on Quality of Service (QoS) and traffic management on the Internet. 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.

Dr. Stoica 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. Dr. Stoica’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. He has created and led several workshops, and subsequently published books including Quality of Service and Peer to Peer Systems in 2003. Dr. Stoica continues his research today and mentors scientists as an Associate Professor of Computer Science at University of California, Berkeley. Over the past 15 years, he has co-authored over 100 papers and technical reports.

He holds a Ph.D. in electrical and computer engineering from Carnegie Mellon University.
