'''Wilberd Leo Johan van der Kallen''' (born 15 January 1947 in [[Nieuwer-Amstel]])<ref>{{cite web|title=XI 5 Wilberd van der Kallen|website= deel 10 : Albert (X 7) — wilberdk.home.xs4all.nl|url=https://wilberdk.home.xs4all.nl/publications_files/deel10.pdf}}</ref> is a Dutch mathematician.

W. L. J. van der Kallen completed his undergraduate study of mathematics and physics at [[Utrecht University]].<ref name=gqt>{{cite web|title=Wilberd van der Kallen (with links to publication list)|website= Geometry and Quantum Theory (GQT) (a national Dutch mathematical research cluster)|url=https://www.gqt.nl/for-researchers/members/wilberd-van-der-kallen/}}</ref> There he received his PhD in 1973 with thesis advisor [[T. A. Springer]] and thesis ''Infinitesimally central extensions of Chevalley groups''.<ref>{{MathGenealogy|name=Wilberd L. J. van der Kallen|id=49613}}</ref> In 1969 Van der Kallen became a teaching assistant in Utrecht University's Mathematics Department and has spent his career there, eventually becoming a tenured professor. His research deals with algebraic K-theory and the representation theory of algebraic groups, among other topics. He has frequently been a visiting professor at [[Northwestern University]] in [[Evanston, Illinois]] and at the [[Tata Institute of Fundamental Research]] in [[Mumbai]].<ref name=gqt/>

He is the author or coauthor of over 60 research articles.<ref name=gqt/> In 1977 he published an analogue of a 1977 theorem of [[Andrei Suslin]]<ref>{{cite journal|author=van der Kallen, Wilberd|title=Another presentation for Steinberg groups|journal=Indagationes Mathematicae (Proceedings)|volume=80|issue=4|pages=304–312|year=1977|doi=10.1016/1385-7258(77)90026-9|url=https://webspace.science.uu.nl/~kalle101/another.pdf|doi-access=free}}</ref><ref>{{cite journal|doi=10.1070/IM1977v011n02ABEH001709|title=On the Structure of the Special Linear Group over Polynomial Rings|year=1977|last1=Suslin|first1=A.
