I lead the NL-eEDM consortium which is a research program to measure the electron's electric dipole moment. The experiment is located at the university of Groningen, and it is a collaborative effort of a team from the Van Swinderen Institute in Groningen with the Vrije Universiteit in Amsterdam, embedded in the Dutch National Institute for particle physics Nikhef. 

The staff involved is Anastasia Borschevsky, Rick Bethlem, Steven Hoekstra, Klaus Jungmann, Rob Timmermans, Wim Ubachs, and Lorenz Willmann.
Below you see a virtual labtour (april 2021) of the NL-eEDM experiment by a number of the PhD students working on the project. In order of appearance, you see Maarten Mooij, Anno Touwen, Parul Aggarwal, Pi Haase, Thomas Meijknecht and Ginny Marshall.
