Ogorzalek. L. Pecora, and K. Yao, IEEE Trans. Circuits Syst. I vol. 48, pp. 1385–1388, Dec. 2001. Ljupco Kocarev (SM’96) received the B.S.E. degree in electrical engineering from the Faculty of Electrical Engineering, Skopje, Macedonia, the M.Sc. degree in electrical engineering from the Faculty of Electrical Engineering, Belgrade, Yugoslavia, and the Ph.D. degree in physics from the Faculty of Natural Sciences and Mathematics, Skopje, Macedonia. Currently, he is an Associate Research Scientist at the Institute of Nonlinear Science, University of Cali- fornia at San Diego, La Jolla, and also a Professor at the Graduate School of Electrical Engineering, Skopje, Macedonia. From 1991 to 1992, he was a Visiting Scientist in the Electrical Engineering Department at the University of California, Berkeley. From 1998 to 1999, he was a Visiting Scientist in the Department of Physics, College of William and Mary, Williamsburg, VA. From 1995 to 1998 he was an Associate Dean of the Faculty of Electrical Engineering, Skopje, Macedonia. His research and professional interests include nonlinear science and its application, synchronization and control of chaos, chaos communication, informa- tion theory and cryptography. He has published in more than 16 different journals, including IEEE TRANSACTION ON CIRCUITS AND SYSTEMS I and II. According to SCI, his work has been cited more than 1200 times. Gian Mario Maggio (S’95–M’99) received the five-year honors degree and the Ph.D degree, both in elec- trical enginnering, from the Politecnico di Torino, Turin, Italy, and University College Dublin, Dublin, Ire- land, in 1995, and 1999, respectively. In 1995, he worked as an Electronic Designer in the Philips R&D Labs, Milan, Italy. In March 1999, Dr. Maggio joined the Institute for Nonlinear Science (INLS), at the University of California at San Diego (UCSD), La Jolla, as a Post-Doctoral Researcher. Since 2000, he is a Research Engineer with the Advanced System Technology (AST) group of STMicroelectronics, Inc., San Diego, CA . He is also currently affiliated with the Center for Wireless Communications at UCSD, and acts as the technical liason AST-UCSD. He held visiting research positions at the Trinity College, Dublin, Ireland, the University of Bristol, Bristol, U. K., the Swiss Federal Institute of Technology, Lausanne, Switzerland, and at the University of California at Berkeley. His main research interests are in the area of nonlinear circuits and systems with applications to wireless communications, iterative-decoding methods and RF oscillators. He has been the recipient of a Marie Curie fellowship, received the Best Paper Award at the 1999 European Conference on Circuit Theory and Design. He served as the Track Chair for Nonlinear Circuits and Systems at ISCAS 2001 (Sydney) and is currently the Secretary of the IEEE Technical Committee on Nonlinear Circuits and Systems (TC-NCAS). He serves as a reviewer for a number of conferences and international journals, and organized the Special Session on application of ISCAS 2001 (Sydney), and is the co-organizer of the Winter School on Nonlinear phenomena in Communication networks. 1057-7122/02$17.00 ©2002 IEEE
