Since early 2018 I am an assistant professor in the Gravity group of the High Energy Physics department at the Institute for Mathematics, Astrophysics and Particle Physics (IMAPP) at Radboud University in Nijmegen, The Netherlands. My research focuses on the development of mathematical tools and numerical methods to explore the structure of spacetime on the smallest of scales, where currently known laws of gravity and quantum mechanics are in dispute.

(Although my name may suggest otherwise, I am a native Dutch speaker. So do not hesitate to address me in Dutch if you wish….)

  Quantum Geometry gallery

  Quantum Gravity is regarded by many as a very abstract topic, but the Random Geometry perspective on Euclidean Quantum Gravity sometimes gives rise to very tangible and aesthetically appealing models. In the Quantum Geometry gallery we share simulation images of random geometries arising in our work.

  Gravity+ track

  Registration is open for our two-year master's programme at Radboud University that includes the specialization ("synergy track") Gravity+. In addition to a standard curriculum in Particle & Astrophysics or Mathematics, students have access to a unique combination of courses on modern aspects of gravity, from classical to quantum, from mathematical to astrophysical, covering black holes, gravitational waves, quantum gravity and much more. Visit gravityplus.org for more information and how to apply.
