{Paulo S. R. Diniz}  was born in Niterói, Brazil. He received the Electronics Eng. degree (Cum Laude) from the Federal University of  Rio de Janeiro (UFRJ) in 1978, the M.Sc. degree from COPPE/UFRJ in 1981, and the Ph.D.  from Concordia University, Montreal, P.Q., Canada, in 1984, all in electrical engineering.

Since 1979 he has been with the Department of Electronic Engineering (the undergraduate dept.) UFRJ. He has also been with the Program of Electrical Engineering (the graduate studies dept.), COPPE/UFRJ, since 1984, where he is presently a Professor. He served as Undergraduate Course Coordinator and as Chairman of the Graduate Department. He is one of the three senior researchers and coordinators of the National Excellence Center in Signal Processing.  He has also received the Rio de Janeiro State Scientist award, from the Governor of Rio de Janeiro state.

From January 1991 to July 1992, he was a visiting Research Associate in the Department of Electrical and Computer Engineering of University of Victoria, Victoria, B.C., Canada.  He also holds the Docent Professor position at Helsinki University of Technology, Espoo, Finland. From January 2002 to June 2002, he was a Melchor Chair Professor in the Department of Electrical Engineering of University of Notre Dame, Notre Dame, IN, USA. His teaching and research interests are in analog and digital signal processing, adaptive signal processing, digital communications, wireless communications, multirate systems, stochastic processes, and electronic circuits. He has published around 200 refereed papers in some of these areas and wrote the books {ADAPTIVE FILTERING: Algorithms and Practical Implementation}, Kluwer Academic Publishers, Second Edition 2002, and {DIGITAL SIGNAL PROCESSING: System Analysis and Design}, Cambridge University Press, Cambridge, UK, 2002 (with E. A. B. da Silva and S. L. Netto).

He was the Technical Program Chair of the 1995 MWSCAS held in Rio de Janeiro, Brazil.  He has been on the technical committee of several international conferences including ISCAS, ICECS, EUSIPCO and MWSCAS. He has served Vice President for region 9 of the IEEE Circuits and Systems Society and as Chairman of the DSP technical committee of the same Society. He is also a Fellow of IEEE ({for fundamental contributions to the design and implementation of fixed and adaptive filters and Electrical Engineering Education}). He has served as associate editor for the following Journals: IEEE Transactions on Circuits and Systems II: Analog and Digital Signal Processing from 1996 to 1999, IEEE Transactions on Signal Processing from 1999 to 2002,  the Circuits, Systems and Signal Processing Journal from 1998 to 2002, and the Circuits and Systems Magazine 2001 to 2003. He was a distinguished lecturer of the IEEE Circuits and Systems Society for the year 2000 to 2001 and is currently distinguished lecturer of the IEEE Signal Processing Society. He belongs to the Editorial board of the the Circuits, Systems and Signal Processing Journal.
