Education
Cleymans obtained his doctorate in physics in 1970 at the University of Louvain (UCLouvain) in Louvain-la-Neuve, Belgium and completed his post-doctoral training in 1977 with habilitation in theoretical and particle-manybody physics at the University of Bielefeld, Germany.

Cleymans' research addressed topics pursued by the ALICE Collaboration at the Large Hadron Collider of the CERN in Geneva, Switzerland. Together with professor Zeblon Vilakazi, he was instrumental in establishing the South Africa-CERN programme, the successor to the UCT-CERN Research Centre.

Cleymans, a theoretical physicists, has  co-authored 299 articles and conference papers with 8,639 citations (status March 3, 2021). In addition,  he is listed on 100 LHC-ALICE experimental works which have earned more than 6,000 citations. He also edited a number of books, reports and conference proceedings. His articles have been published in a variety of international journals, among others the European Physical Journal, Physical Review and Physics Letters. Over the years he supervised 24 MSc and 17 PhD students.
