Thijs Laarhoven

Eindhoven University of Technology


Hi, and welcome to my website! I am Thijs Laarhoven, and currently I am a postdoctoral researcher at the Eindhoven University of Technology in the Netherlands, in Nikhil Bansal's group. Previously I was a postdoc at IBM Research in Zurich, Switzerland, working on lattice-based cryptography in the group of Vadim Lyubashevsky. Before that I obtained my BSc, MSc, and PhD degrees at the Eindhoven University of Technology, under the inspired supervision of Benne de Weger.
