“We think basis-free, we write basis-free, but when the chips are down we close the office door and compute with matrices like fury”

Short academic bio

I received my PhD, supervised by Ryszard Nest, from the University of Copenhagen in 2008. I then spent 3 years as postdoc (partially funded by a DFF postdoctoral grant) at the University of Göttingen working in the group of Thomas Schick, and was in 2011 selected for a postdoc position at KU Leuven working with Stefaan Vaes. In 2013, I returned to Denmark as assistant professor at SDU (funded by a personal research grant from the Lundbeck Foundation), and was subsequently promoted to associate professor in 2015 and full professor in 2021. My research revolves around the interplay between operator algebras and geometric group theory, with particular emphasis on quantum groups, von Neumann algebras, quantum metric spaces, cohomology, L²-Betti numbers, amenability, property (T) and related notions. I am currently in charge of the project Classical and Quantum Distances and part of the project 'Operator algebras, groups and quantum spaces', both of which are funded by funded by the Independent Research Fund Denmark.
