Research Focus

Adaptive filtering, Statistical signal processing, spectrum analysis and estimation, networked dynamic state estimation.


Dr. Lev-Ari received the BS (Summa Cum Laude), and the MS degrees in Electrical Engineering from the Technion, Israel Institute of Technology, in 1971 and 1978, respectively; and the PhD in Electrical Engineering from Stanford University, Stanford, CA, in 1984.

Dr. Lev-Ari was a research scientist with Integrated Systems, Inc., Palo Alto, CA from 1982 to 1984. During 1985 he held a joint appointment as an adjunct research professor of Electrical Engineering with the Naval Postgraduate School, Monterey, CA and as a research associate with the Information Systems Laboratory at Stanford. He stayed at Stanford as a senior research associate until 1990, when he joined Northeastern University. During 1994-1996 he was the Director of the Communications and Digital Signal Processing (CDSP) Center at Northeastern University. Professor Lev-Ari served as an Associate Editor of Circuits, Systems and Signal Processing, and of the IEEE Transactions on Circuits & Systems I. He has authored/coauthored over 50 journal publications, 11 book chapters and over 90 conference papers. He is a member of SIAM, and a Fellow of the IEEE.

Dr. Lev-Ari has supervised the research of 22 MS students and 21 PhD candidates. His research interests include adaptive filtering under the non-stationary regime, dynamic time-frequency analysis, and multi-rate/multi-sensor networked state estimation; with applications to identification of time-variant systems, customized dynamic phasors, dynamic power decomposition, and adaptive power flow control in polyphase power systems. His past research has involved a number of mathematical techniques and a variety of applications in signal processing, including: model-based spectrum analysis and estimation for non-stationary signals; extension of maximum-entropy techniques to multi-dimensional signal processing; characterization of structured matrices; and Markov renewal models for non-stationary signals.
