Niels Samwel

Information

Currently, I work as an Embedded Security Engineer at Intrinsic ID in Eindhoven. Before that I was a PhD student supervised by Prof. Lejla Batina and Prof. Joan Daemen in the Digital Security group of the Radboud University in Nijmegen, The Netherlands. My research focus is on side-channel attacks and countermeasures on embedded devices. During the summer and fall of 2019 I was a hardware engineering intern in the gChips team at Google in Mountain View CA, United States.
