Jan Verelst (born ca 1960) is a Belgian computer scientist, Professor and Dean of the Department of Management Information Systems at the University of Antwerp, and Professor at the Antwerp Management School, known for his work on Normalized Systems.

Biography
Verelst obtained his Ph.D. in Management Information Systems in 1999 from the University of Antwerp with a thesis entitled "De invloed van variabiliteit op de evolueerbaarheid van conceptuele modellen van informatiesystemen" (The impact of variability on the evolvability of conceptual models of information systems).

After his graduation he was appointed Professor of Systems Development Methodology at the Faculty of Applied Economics of the University of Antwerp, and Dean of the Department of Management Information Systems. He is also appointed as Professor at Antwerp Management School.

His research interests are in the field of "conceptual modeling of information systems, evolvability, and maintainability of information systems, empirical software engineering, and open source software", specifically the development of Normalized Systems, and its development methodology.
