Géza Kolumbán (Fellow, IEEE) received his M.S. and Ph.D. degrees from the Technical University of Budapest in 1976 and 1990, respectively, and his C.Sc. and D.Sc. degrees from the Hungarian Academy of Sciences in 1990 and 2004, respectively, and his Dr.habil degree from the Budapest University of Technology and Economics in 2005. He is an IEEE fellow (2005) with the citation: "for contributions to double sampled phase-locked loops and noncoherent chaotic communications."

After his graduation, he worked with the Fine Mechanical Enterprise, Hungary, where he developed local generators, microwave transistor power amplifiers and VCO circuits for high-capacity microwave analog radio relay systems. He joined the Research Institute for Telecommunications, Hungary, in 1980, where he was involved in many system engineering projects such as SCPC-type satellite telecommunications system, microwave satellite up- and down-converters, low-capacity microwave digital radio system, etc. He headed a group of engineers, whose duty was to develop frequency synthesizers and local generators for frequency hopping spread spectrum and satellite systems.

He spent one year with Bilkent University in Turkey (1991-92) and another year with the Eastern Mediterranean University in Cyprus (1992-93). He returned to the Budapest University of Technology and Economics (BUTE) in 1993, where he is a full professor and the head of Chaotic Systems Team at the Department of Measurement and Information Systems (MIT).

As the head of Chaotic Systems Team he has shown that chaos exists in analog phase-locked loops, elaborated the theory of chaotic waveform communications and established noncoherent chaotic communications as a brand new research direction. He developed DCSK and FM-DCSK, the most popular chaotic modulation schemes.

Two of his papers, co-authored with Profs. M.P. Kennedy and L.O. Chua, have been ranked in top-cited IEEE Trans. CAS-I articles. 63 of his publications have been cited more than 800 times by independent authors.

He has been a visiting professor and researcher to the Electronics Research Laboratory, UC Berkeley, The Hong Kong Polytechnic University (PolyU), INSA-LATTIS Laboratory, Toulouse, France, University College Dublin and Cork, Ireland, EPFL, Switzerland, TU Dresden, Germany and the Hong Kong City University.

His current research and professional interests include nonlinear dynamics of phase-locked loops, frequency synthesis by phase-locked loop, computer simulation of complex systems, chaotic and UWB radio communications, implementation of automated manufacturing lines and automated testing systems, both providing traceability.
