After completing his primary education at the Pozsony-Püspöki Hungarian Primary School and secondary education at the Dunaszerdahely High School in Bratislava, he continued his studies at the Faculty of Chemical Engineering at the Slovak Technical University (STU), graduating in 1975 with an engineering degree in chemical automation. He has been working as a university lecturer at this faculty since 1975.

He defended his candidate thesis in 1983 in the field of process control, focusing on the analysis and optimal control of distributed parameter systems. In 1994, he habilitated in the field of process control and was appointed as an associate professor. In 2005, he achieved the title of full professor in the same field, particularly for his development of the application of methods of artificial neural networks in the design of adaptive controllers.

From 1994 to 1997, he served as the head of the Automation Department at the Faculty of Chemical Engineering at STU. From 2008 to 2011, he was the director of the Institute of Engineering Studies at STU.

He has spent several years at foreign universities, establishing and maintaining excellent professional relationships that continue to this day. As a result, he is a member of numerous Slovak, Hungarian, and international scientific societies, including the Slovak Chemical Engineers Association, the Slovak Cybernetics Society, the Hungarian Academy of Sciences, the New York Academy of Sciences, the European Biotechnology Federation, and the European Federation of Chemical Engineering (where he is the Slovak representative in the CAPE working group).

He has published over 200 works (140 of which are in English), including scientific monographs, book chapters, research articles, textbooks, notes, and edited volumes.

As a minority politician, he is a member of the Hungarian Community Party (MKP) and has held the following positions: 1990-2006 – local government representative, 1998-2006 – Deputy Mayor of Pozsony-Püspöki, 2006-2007 – Slovak Ambassador to Sweden, and 2009-2013 – MKP Member of the European Parliament.
