Josse van Dobben de Bruyn
I am a mathematician, currently working as a postdoc with David E. Roberson at the Technical University of Denmark (DTU). Before that, I was a PhD student at TU Delft in the Netherlands under the supervision of Dion Gijswijt.
My current research focuses on interactions between graph theory, quantum information theory, and quantum groups. My broader interests include algebraic combinatorics, functional analysis, quantum information theory, and quantum groups.
My name is Dutch and consists of three parts: {First}{von}{Last}{Jr.} = {Josse}{van}{Dobben de Bruyn}{}. It should be alphabetized under “Dobben”.
