Lajos Ronyai

After graduating, he started working at the Computer Science and Automation Research Institute (SZTAKI) of the Hungarian Academy of Sciences; he has been a senior research associate since 1987.
Between 1995 and 2008, he was the head of the SZTAKI Informatics Laboratory. In 2008, he took over the leadership of the Computer Science Research Group of the research institute. In 1999, he was appointed as a scientific consultant.

In addition to his position at the research institute, he was a contracted lecturer at the Budapest University of Technology (BME) between 1990 and 1992, then a part-time lecturer from 1992. He became a habilitated lecturer in 1996 and was appointed as a university professor in 1998. He headed the Department of Algebra at BME from 2001 to 2014. He was a Széchenyi Professorship Fellow between 1998 and 2001. He worked as a visiting lecturer at the University of Oregon (1984-1985) and the University of Chicago (1987, 1988-1989).

He defended his thesis for the degree of candidate of mathematical sciences in 1987 and his academic doctoral thesis in 1999 in the field of mathematics and computer sciences. In 2001, he was elected a corresponding member of the Hungarian Academy of Sciences, and in 2007, a full member.

He has been a member of the Computer Science and Informatics Committee of the Hungarian Academy of Sciences since 1993. He has been a member of the Bolyai János Mathematical Society since 1979. From 2007 to 2012, he also worked in the European Research Council's expert panel on informatics and computer science (PE6). Between 2011 and 2017, he was a member of the Doctoral Council of the Hungarian Academy of Sciences.
He was previously a member of the editorial board of the Journal of Algorithms and Acta Mathematica Hungarica, then of the Matematikai Lapok, Alkalmazott Matematikai Lapok and Magyar Tudomány.

His research interests include applications of algebra, primarily algorithms and symbolic computations within computer science, and discrete mathematics. In the field of algebraic and arithmetic algorithms, he contributed to the development of the algorithmic theory of finite-dimensional algebras.

He is the author or co-author of more than a hundred scientific publications. He is the co-author of the university textbook Algorithms, published in 1998.

His awards: Academic Youth Award (MTA, 1985); Kalmár Award (NJSZT, 1997); Ottó Benedikt Award (SZTAKI, 2000); Bolyai Farkas Award (MTA, 2000); Award of the Faculty of Informatics of the University of Debrecen (2006); Tibor Szele Memorial Medal (BJMT, 2015); Széchenyi Award (2019).
