From 1993 to 1998 he was also acting director of the interdivisional program in statistics.

He studied at Leiden University, where he received his propedeutic examination psychology summa cum laude in 1964; his candidate examination psychology summa cum laude in 1967; and his doctoral examination psychology summa cum laude in 1969. In 1973 he received his PhD cum laude with a thesis entitled "Canonical Analysis of Categorical Data" advised by John P. van de Geer. The thesis described an alternative organization of multivariate data analysis techniques, which formed the basis for the Gifi group in Leiden and the Gifi system more broadly.
