John Apostolopoulos

Lab Director, Mobile & Immersive Experience Lab at Hewlett-Packard Laboratories


John Apostolopoulos is a Distinguished Technologist and the Director of the Mobile and Immersive Experience Lab (MIX Lab), in HP Labs, directing about 75 researchers in Palo Alto, USA, Bangalore, India, and Bristol, England. The goals of the MIX Lab are (1) to create compelling networked media experiences that fundamentally change how people communicate, collaborate, socialize and entertain, (2) to develop multimedia technologies to deliver interactive, mobile, and immersive audio-visual experiences, (3) to develop natural and intuitive forms of interaction between people and technology, (4) to create the next generation of 2-D and 3-D display technologies and information surfaces for mobile and immersive environments, and (5) to create technologies that will make IT relevant, affordable and simple to consume for HP's next billion customers in rapidly emerging markets such as India and China.

His personal primary research interests include mobile and immersive communications, multimedia cloud computing, and improving the reliability, fidelity, scalability and security of multimedia communications over wired and wireless networks. His work on transcoding in the middle of a network while preserving end-to-end security (secure transcoding) has recently been adopted by the JPEG-2000 Security (JPSEC) standard.

Apostolopoulos received his B.S., M.S., and Ph.D. degrees in electrical engineering and computer science from MIT. In graduate school, he worked on the U.S. Digital TV standard and received an Emmy Award Certificate for his contributions.

Apostolopoulos was named “one of the world’s top 100 young (under 35) innovators in science and technology” (TR100) by MIT Technology Review in 2003, and has received a number of best paper awards. He was named an IEEE Fellow in 2008.

He also teaches and conducts joint research at Stanford University, where he is a Consulting Associate Professor of Electrical Engineering, and he is a frequent visiting lecturer in MIT’s Department of Electrical Engineering and Computer Science.
