Alberto Tosi received the master’s degree (cum laude) in electronics engineering and the Ph.D. degree (cum laude) in information technology engineering from the Politecnico di Milano, Milan, Italy, in 2001 and 2005, respectively. He was an Assistant Professor from 2006 to 2014. He has been an Associate Professor of Electronics with Politecnico di Milano since 2014. He currently works on silicon and InGaAs/InP single-photon avalanche diodes (SPADs).
He is currently working on the design and development of novel SPADs, both exploiting standard planar silicon CMOS technologies and innovative hetero-epitaxies of III-V materials and germanium-on-silicon, for extending the photon counting to the near-infrared (up to 1700 nm) spectral ranges.
His research activity includes arrays of SPADs for 2-D and 3-D applications and time-correlated single-photon counting electronics.
In 2004, he was a Student with the IBM T. J. Watson Research Center, Yorktown Heights, NY, working on optical testing of CMOS circuits.
He is the principal investigator for POLIMI-DEIB in the projects “DARPA REVEAL: Scene Recovery using an extended Plenoptic Function” (University of Wisconsin subcontract PRJ 144 AAA8584), “micro-crystals Single Photon InfraREd detectors (microSPIRE)” (H2020 FETOPEN-RIA-2017-1 g.a. 766955), “Smart optical and ultrasound diagnostics of breast cancer (SOLUS)” (H2020 ICT-29-2016-RIA, g.a. 731877) and “Laser and Ultrasound Co-Analyzer for thyroid nodules” (ICT-28-2015, Cross-cutting ICT KETs, g.a. 688303). He was also the principal investigator for POLIMI of the projects “Optical metrology for quantum-enhanced secure telecommunication” (EURANET EMPIR 14IND05 MIQC2), “Advanced Laser Ranging Technologies for Altimetry” (ESA ITT AO 1-7483/13/NL/CP) and “Development of high-performance single-photon detectors”, European Metrology Research Programme (EMRP) Grant IND06-REG2 – Researcher Excellence Grant in reference to JRP: IND06 MIQC. He is a participant of the project “Dependability Engineering Innovation for CPS (DEIS)” (H2020 ICT-01-2016, g.a. 732242) and he was a participant of the project “Microelectronic Single-Photon 3D Imaging Arrays for low-light high-speed Safety and Security Applications (MiSPIA)” (FP7-ICT-2009.3.7, g.a. 257646) and of the project “Quantum Interfaces, Sensors, and Communication based on Entanglement (Q ESSENCE)” (FP7-ICT-2009.8.2, g.a. 248095), besides actively working in other projects funded either by the European Commission or by the Italian Ministry.
He is co-author of more than 240 papers on peer-reviewed journals and conference proceedings, he is the co-inventor of 3 patents for improving the optical testing of integrated circuits and he filed 2 additional patent applications.
His H-index is 34 (according to Scopus, author ID 35499994500).
He teaches the course “Elettronica” (10 credits) for Biomedical Engineering since 2009.
Since 2014 he is member of the Technical Program Committee for the Single Photon Workshop (SPW) and he is the General Chair of the Single Photon Workshop that will be organized in Milano (Italy) in October 2019.
