A group of trainees visited the ECN facilities of TNO in Delft in February 2020. We had the opportunity to listen to a presentation about the innovative projects carried out by the researchers working there and to see the laboratories where they conduct their experiments every day. We gave a presentation to let them better understand how the PDEng is structured, which kind of design projects we work on and what we do to build our professional and social network. It was definitely an inspiring day!
