I'am an electrical engineeringPhD student in Polytechnic of Milan. My research topic is focused on Laser Interferometry and with particular reguard to AM and FM modulation self-mixing one. This specific measurement technique is a part of those known as Non-Desctructive testing (NDT). From 1 to 5 July 2019, I have been attending an intensive course on Science, technology, society and Wikipedia for PhD students at the Polytechnic University of Milan (PoliMi), Italy, with the collaboration of Wikimedia Italia.
