Dr. Vangelis Karkaletsis, was intrviewed by Y.Rizopoulos for Tech Talks Central during Researcher’s Night 2015. Diving into the quite significant educational activities of Greek Research Center NCSR Demokritos, he focuses on the ever increasing synergies it holds with American and European universities in joint PhD programs, the classic annual summer school for Greek students that this year turns 50 (!), as well as the successful biannual international school for young researchers. He also talks about the strengthening of international research co-operation in NCSR; he reveals a lot about their ambitious plans for the future and, sure enough, he doesn’t forget to speak about the main cause for this round of interviews, the European Researchers’ Night, that will take place in late September 2015.
