Dr Alessandro Ruggeri (male), received his PhD in Information Engineering from Politecnico di Milano (POLIMI) in 2015. He is currently the Chief Technology Officer of Micro Photon Devices Srl, after working some years as a senior development engineer and dealing with the design of advanced electronic circuits, FPGA programming and experimental characterization of avalanche photodiodes for single-photon counting, both in Silicon and InGaAs/InP. Previously, he was a Research Assistant in the Department of Electronics, Information and Bioengineering at POLIMI. In the summer of 2014, he worked at the IBM T. J. Watson Research Center, Yorktown Heights, NY, where he worked on the characterization of ULSI circuits using optical (non-invasive) testing. His main research interest is in the development of electronics for single-photon diodes, both in the visible and near-infrared, for biomedical applications, physics studies, quantum communications, and quantum sensing.
