He was a visiting professor in the USA, Germany, Egypt, Canada and France. Since 2004 he has been an honorary doctor of Vilnius University, since 2010 of ELTE, since 2013 of Nguyen Tat Thanh University (Ho Chi Minh City, Vietnam). Since 2008 he has been a professor emeritus of ELTE TTK.

His main research area is analytic and probability number theory. His achievements in the field of fractal geometry are significant. He has published nearly 400 publications.

He defended his candidate of mathematical sciences thesis in 1965 and his academic doctoral thesis in 1969. He is a member of the Hungarian Academy of Sciences' Mathematics and Informatics and Computer Science Committee. He has been a corresponding member of the Hungarian Academy of Sciences since 1979, a full member since 1985; he was a member of the Supervisory Board from 1995 to 2004. He is the founding editor-in-chief of the "Annales Universitatis Scientiarum ELTE Sectio Computatorica" (AC) (with a dedicated publication on his 70th birthday).
