Roger J-B Wets

The legal name of Roger J–B Wets lacks periods in the middle name.^[1]

Career

Raised in Belgium, Roger J–B Wets was encouraged by Jacques H. Drèze to study optimization with George Dantzig at the operations research program at the University of California, Berkeley.^[2] Other students included Richard W. Cottle, soon a leader in quadratic programming and the linear complementarity problem, Ellis Johnson, soon a leader in integer programming and combinatorial optimization, and Richard Van Slyke, soon a leader in computational control theory and large-scale optimization.^[3]

Wets is now professor at the mathematics department of the University of California, Davis.

Wets and Claude Lemaréchal were each awarded the George B. Dantzig Prize for "original research that has had a major impact on the field of mathematical programming" in 1994 by the Society for Industrial and Applied Mathematics (SIAM) the Mathematical Programming Society (MPS).

^ Wets stated that he believed that he took the only course in operations research available (at that time) in Western Europe, from Jacques H. Drèze at the Université Catholique de Louvain. Because of Drèze's suggestion to study with Dantzig at Berkeley, Wets credits Drèze as being responsible for getting him into the field of optimization. (Page 3) Aardal, Karen (July 1995).
