Between 1951 and 1969, he was a scientific associate and later a senior associate of the Electrification Research Committee and its successor, the Electric Power Industry Research Institute (VEIKI). Between 1951 and 1969, he was the head of department at VEIKI, and from 1958, he was also an expert at the Instrument Industry Research Institute.
As a member of the VEIKI, he was one of the pioneering developers of relay protection systems for the Hungarian energy system; he later became the head of the department dealing with mathematical-control theory problems at the time (alongside Tamás Frey). His department also initiated pioneering research in computational linguistics.

Between 1969 and 1990, he was a senior research fellow and then head of department at the Computer Science and Automation Research Institute (SZTAKI) of the Hungarian Academy of Sciences.
Meanwhile, between 1964 and 1965, he was a visiting researcher in the USA on a Ford scholarship.

He began his teaching activity at BME in 1978. He played an important role in the planning and launch of the technical computer science program at the Faculty of Electrical Engineering (VIK) of BME; he was the continuous instructor of the subject Formal Languages. He also initiated the teaching of mathematical linguistics at BME.
He is a founding member of the Department of Mathematics and Computer Science as an assistant professor, then as an honorary associate professor from 1989, and as an invited lecturer from 1993.
In 1964 he obtained the title of Candidate of Technical Sciences.

He has achieved new international results in the field of formal languages and programming systems, as well as in the study of various compilers. He is the author of several books.

His awards include: Miksa Déri Prize (Hungarian Electrotechnical Association, MEE, 1970); Széchenyi Prize (2005).
