His early studies were determined by Márton Sain, who taught at the Lónyai Street Grammar School in Budapest, and Károly Benkő, a chemistry teacher from Szeghalom who fled from the Royal Hungarian Franz Joseph University in Cluj.

He helped the research and teaching activities of the computational chemistry group led by Béla Viskolcz at the Department of Chemical Informatics (SZTE) as an emeritus professor until 2015.

Since then, he has been a visiting professor in many countries around the world: in Canada, Argentina, Japan, China, England, Germany, France, Spain, Italy and, of course, Hungary.

(POLYATOM[4] was the first software package for ab initio calculations using Gaussian orbitals, developed in John C. Slater's Solid State and Molecular Theory Group.)

[5] Later, he studied the theoretical background of the stereochemical consequences of electron pairs and polar bonds in side-by-side positions (Edward-Lemieux, also known as the anomeric effect).

[8] In 1976, using the model compound PH5, he studied Berry pseudorotation (BPR) and turnstile rotation (TR) describing the intramolecular ligand exchange reaction of phosphoranes.

Although he was the author or editor of a large number (550) of scientific publications and 14 books, and according to Web of Knowledge, his total references exceed 7,500, he considered his students to be his most important achievement.
