Nicola Massari received the Laurea degree in electronic engineering from the University of Padova. Since 2000 he has worked with FBK as a researcher in the IRIS group, developing smart image sensors and sensor interfaces. In these years of activity he has been involved in national and European projects as mixed-signal designer mainly focused on the design of CMOS smart optical sensor and in particular with in-pixel processing. His main interests are ultra-low power vision sensors with processing capability, and special sensor architecture based on single photon avalanche diode.
