Yesterday, we kicked off our last training school, held at the University of Twente. After introductory words from Prof. Andrés Alayón Glazunov and Prof. André Kokkeler, the received a very interesting presentation about entrepreneurship. Next, a lecture on 3GPP standardization was given, really demystifying the process for our ESRs and providing valuable tools to use standardization documents more effectively in research. Thank you very much to our speakers for such interesting content. ESRs
