John Apostolopoulos

John Apostolopoulos received his B.S., M.S., and Ph.D. degrees in EECS from MIT. He joined Hewlett-Packard Laboratories in 1997 where he is currently Lab Director of the Multimedia Communications and Networking Lab, and a Distinguished Technologist. Previously he was the R&D Manager for the Streaming Media Systems Group. He also teaches and conducts joint research at Stanford University where he is a Consulting Associate Professor of electrical engineering, and is also regularly a visiting lecturer at MIT EECS. During graduate school he also spent summers at AT&T Bell Labs and Jet Propulsion Laboratory. In graduate school he worked on the U.S. Digital TV standard, and received an Emmy Award Certificate for his contributions. He received a best student paper award for part of his Ph.D. thesis, the Young Investigator Award (best paper award) at VCIP 2001 for his work on multiple description video coding and path diversity, was named "one of the world's top 100 young (under 35) innovators in science and technology" (TR100) by Technology Review in 2003, and was co-author for the best paper award at IEEE ICME 2006 on authentication for streaming media. His work on media 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. He currently serves as chair of the IEEE Image and Multidimensional Signal Processing (IMDSP) technical committee, member of the Multimedia Signal Processing (MMSP) technical committee, on the editorial board of IEEE Signal Processing Magazine, and recently was co-guest editor of special issues on "Multimedia over Broadband Wireless Networks" (IEEE Network) and "Network-Aware Multimedia Processing and Communications" (IEEE Journal on Selected Topics in Signal Processing), general co-chair of VCIP'06, and technical co-chair for IEEE ICIP'07. His research interests include improving the reliability, fidelity, scalability, and security of media communication over wired and wireless packet networks. He recently became a Fellow of the IEEE for his "contributions to the principles and practice of video communications and secure media streaming".

John Apostolopoulos received his BS, MS, and PhD degrees in Electrical Engineering and Computer Science from MIT in 1989, 1991, and 1997. His graduate school research was in the areas of signal processing and video/image processing and compression. For his MS thesis, John developed a MC-wavelet based algorithm for video compression as part of an All-Digital HDTV system. For his PhD thesis he developed a critically sampled wavelet representation for representing multi-dimensional signals defined over arbitrary regions of support. In graduate school, he also worked on the design of the video compression algorithms for the MIT/General Instrument Channel-Compatible DigiCipher (CCDC) HDTV system and the Grand Alliance HDTV system as part of the U.S. HDTV standardization activities. His MS and PhD theses as well as the digital TV work was performed within the Advanced Television and Signal Processing Group led by Prof Jae Lim. 

During his graduate years, John worked two summers at the Jet Propulsion Laboratory on deep-space optical communications and one summer at AT&T Bell Laboratories on very-low-bit-rate video compression. 

In graduate school he held an AT&T Bell Laboratories PhD fellowship, received an Emmy Award Certificate for contributions to the Grand Alliance Digital TV Standard, and received a best student paper award for a paper on coding of arbitrarily shaped objects in an image.   He received the Young Investigator Award (best paper award) at VCIP'2001 for his paper on multiple description video coding and path diversity for reliable video communication over lossy packet networks. In 2003 he was named "one of the world's top 100 young (under 35) innovators in science and technology" (TR100) by MIT's Technology Review.

John joined Hewlett-Packard Laboratories in Palo Alto, CA, in December 1997, where he is currently a Principal Research Scientist. His current research interests are in the general areas of multimedia communication, digital video processing, and mobile streaming media content delivery networks, with a particular emphasis on reliable and secure video communication and streaming over packet networks and wireless links. John is a member of IEEE, an Associate Editor for IEEE Transactions on Image Processing and for IEEE Signal Processing Letters, HP's primary representative to MPEG, a member of JPEG, a member of IEEE Image and Multidimensional Digital Signal Processing (IMDSP) Technical Committee, and a Consulting Assistant Professor at Stanford where he has been doing research and teaching the graduate course Digital Video Processing (EE392J) since 1999. John enjoys teaching, and he is also regularly a visiting lecturer at MIT EECS. He has recently been heavily involved with the JPEG-2000 Security (JPSEC) standardization activity.
