Research interests

I am a theoretical physicist working on Majorana fermions, topological phases of matter and quantum computing. I am working as a team leader at QuTech, where I lead the Quantum Tinkerer group together with Anton Akhmerov. Previously, I was a post-doc in the mesoscopic physics group of Carlo Beenakker in Leiden. My main research interests are: Other interests of mine include
