Research
Interests
Laurens has co-authored more than 15 peer-reviewed research publications, several of them in key scientific journals like Nature / Science. His expertise is in nano-fabrication of GaAs/AlGaAs quantum dots and Si/SiO2 MOSFETs. Moreover, he has a background in low-temperature, high-frequency measurements. Laurens is a lead experimental research fellow in the top-down fabrication program, focussing on coherent control of electron spins in silicon devices.
