Curriculum

Martin Hasler received the Diploma in 1969 and the PhD degree in 1973 from the Swiss Federal Institute of Technology, Zurich, both in physics.

He continued research in mathematical physics at Bedford College, University of London, from 1973 to 1974. At the end of 1974 he joined the Circuits and Systems group of the Swiss Federal Institute of Technology, Lausanne, where he was given the title of a Professor in 1984. He became associate and full professor, respectively, in 1996 and 1999..

During the 70's, his research was concentrated on filter theory and design, in particular active and switched capacitor filters. In 1979, he started research in nonlinear circuit theory, a new field for his institution. The main concern in the beginning was qualitative analysis of dynamic, and later also of resistive circuits. In this context, he became interested in chaotic behavior of electric circuits. Later, he also became interested in artificial neural networks, as a special class of nonlinear circuits. He also started research on modeling of nonlinear circuits and systems, as a complement to nonlinear circuit and system analysis. Application areas are in high-temperature superconductor modelling, speech recognition and biomedical engineering. A considerable research effort goes into the application of chaotic dynamics in information transmission and signal processing. Recently, he became interested in the information processing in the brain.

He is the author and coauthor of about 120 research papers and 5 books, among them: M. Hasler, J. Neirynck, Nonlinear circuits by Artech House, Boston, 1986 and Y.Kamp, M.Hasler, Recursive neural networks for associative memory by Wiley and Sons, London, 1990. He obtained the best paper award of the International Journal on Circuit Theory and Application in 1986 and 1996.

He has been the Editor of the IEEE Transactions on Circuits and Systems, Part I: Fundamental Theory and Applications from 1993 till 1995. He is also a member of the Editorial Board of International Journal of Circuit Theory and Applications and the International Journal on Bifurcations and Chaos.

He is a Fellow of the IEEE. He was the chairman of the Technical Committee on Nonlinear Circuits and Systems IEEE CAS Society from 1990 to 1993.  He was the Chairman of  ISCAS 2000, Geneva, Switzerland. He was a member of the Board of Governors of the IEEE CAS Society and currently he is Vice-President for Technical Activities of this society.

He is a member of the Scientific Council of the Swiss National Science Foundation since Jan. 2000.
