Antonio Ortega

Antonio Ortega received the Telecommunications Engineering degree from the Universidad Politecnica de Madrid, Madrid, Spain, in 1989, and the Ph.D. degree in electrical engineering from Columbia University, New York, NY, in 1994, where he was supported by a Fulbright scholarship. In 1994, he joined the Electrical Engineering Systems Department at the University of Southern California, where he is currently a Professor and an Associate Chair of the Department. He is a Senior Member of IEEE, and a Member of ACM. He has been Chair of the Image and Multidimensional Signal Processing (IMDSP) technical committee and a Member of the Board of Governors of the IEEE SPS, 2002. He was the technical program Cochair of ICME 2002, and has served as the Associate Editor for the IEEE Transactions on Image Processing and the IEEE Signal Processing Letters. He received the NSF CAREER Award, the 1997 IEEE Communications Society Leonard G. Abraham Prize Paper Award, and the IEEE Signal Processing Society 1999 Magazine Award. His research interests are in the areas of multimedia compression and communications. His recent work is focusing on distributed compression, multiview coding, compression for recognition and classification applications, and wireless sensor networks.
