Mathematician, born 1948.03.24 in Makó (Hungary).
Since 1987, he is a full professor at the University of Basilicata (Italy).

In 1971 he graduated at the Eötvös University.
In 1972 he received in 1972 from the University of Budapest a Ph.D. in mathematics.
In 1973 on a postdoc grant, he studied at the Research Center of the Accademia dei Lincei in Rome.
In 1976 he was awarded the Grunwald Prize of the János Bolyai Mathematical Society.
In 1980 he received the Candidate of Sciences degree and in 2000 the Doctor of Sciences degree from the János Bolyai Mathematical Society.
In 2008 he received the Euler Medal of the Institute of Combinatorics and its Applications (ICA), (Canada).
In 2014 he awarded the Doctor Honoris Causa at the University of Szeged.

He is working actively in doctoral schools of several universities.
Since 2006, he has been coordinating the joint “János Bolyai Doctoral Seminar” of Szeged and several Italian universities.
He was a visiting professor at several universities, including the University of Sussex and the University of Delaware.

His research involves the theory of ovals and their higher-dimensional generalizations over finite fields. One topic of his research is the collineation groups of ovals and embedding problems for arcs in ovals; these investigations have applications in coding theory and are related to the Hasse-Weil bound for elliptic curves. He also works on algebraic curves over finite fields and their automorphism groups, translation planes, finite Möbius planes, finite Minkowski planes, and elliptic curve cryptography.
In the late 1970s he worked with Beniamino Segre.
