According to Wikipedia, Joseph Adolphe François Thas is a Belgian mathematician, who works on combinatorics, incidence geometry and finite geometries. Thas received in 1969 his PhD from Ghent University under Julien Bilo with thesis der 3x3-matrices met elementen in een algebraïsch afgesloten veld K. Thas showed how to extend projective geometry and cross-ratios with the concept of a projective line over a ring.
