Stefan Langerman false Swarzberg is a Belgian computer scientist and mathematician whose research topics include computational geometry, data structures, and recreational mathematics. He is professor and co-head of the algorithms research group at the Université libre de Bruxelles (ULB) with Jean Cardinal. He is a director of research for the Belgian Fonds de la Recherche Scientifique (FRS–FNRS)[1][2].

Education and career

Langerman left his Belgian secondary school at age 13 and was admitted by examination to the École polytechnique of the Université libre de Bruxelles. He studied

licenciate.[3]

After working as a user interface programmer for the Center for Digital Molecular Biophysics in Gembloux,[3] he moved to the US for graduate study at Rutgers University, where he earned a master's degree and then in 2001 a PhD. His doctoral dissertation, Algorithms and Data Structures in Computational Geometry, was supervised by William Steiger.[3][4] Next, before joining ULB and FNRS, Langerman worked as a postdoctoral researcher at McGill University[3] with computational geometry researchers Luc Devroye and Godfried Toussaint.

Research

Langerman's research is primarily in computational geometry. Known for novel and often playful results such as "Wrapping the Mozartkugel"[WM] which earned him the moniker of a computational chocolatier,[5][6] Langerman has made a number of scientific advances in fields as diverse as musical similarity,[MMS] polycube unfolding,[CUP] computational archaeology,[WBT] and protein folding.[7] Langerman's work in data structures includes the co-invention of the queap[Q] and the introduction of the notion of retroactive data structures,[RDS] a generalization of the concept of a persistent data structure. He is the author or more than 240 publications,[8] and has led scientific missions with other western scientists to collaborate with colleagues in North Korea.[9]

Family

Langerman is also the founder of Langerman SPRL, a Belgian colored-diamond company based on the collection of Langerman's father Arthur Langerman, a dealer of colored diamonds who is also noted as an author and as a collector of anti-semitic posters.[10] He is the co-author with his father of a paper on

Morpion solitaire, written jointly with another father-and-son pair, Martin Demaine and Erik Demaine.[MS] Both Stefan Langerman and his father are members of the Board of Trustees of the Arthur Langerman Foundation, a non-profit organization based in Berlin, which makes its founder’s unique collection of visual antisemitica available for research, educational and exhibition purposes.[11]
