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

[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.

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.

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.
