got the master and PhD degrees in electrical engineering from the University of Bologna. From 1995 to 1998 he was assistant professor at the University of Ferrara. Since 1998 he is associate professor at the University of Bologna. He teaches the course of Predictive Maintenance and Diagnostics of Electrical Systems. As a Ph.D. student and later on assistant professor, he worked in power quality, with an emphasis on harmonic distortion. He developed tools to predict harmonic currents injected by

... AC/DC converters, and models for probabilistic harmonic flow. Besides, he investigated flicker due to arc furnaces, active and passive filters, non-parametric load forecasting tools. He became associate professor in 1998 and, since then, he works on endurance modelling and diagnostics of insulation systems. His research focuses on partial discharges detection and identification in diverse types of apparatus (cables, rotating machines, transformers, GIS) through innovative detection system. Artificial intelligence techniques are used to achieve PD source identification. Currently, the physics of partial discharge phenomena and the degradation rate of electrical insulation systems subjected to PWM voltage waveforms is his principal line of investigation. Insulation systems of low voltage rotating machines, resin-cast/oil-filled transformers, and silicone gels are considered. In particular, the impact of thermal aging, temperature and pressure on inception of and endurance under partial discharge under repetitive surges is dealt with in depth due to its strong impact in the automotive and aerospace industry. As a new line of investigation, a contract was signed recently with STMicroelectronics concerning the evaluation of insulation systems for microelectronics. Other topics are the influence of VLF voltage waveforms on PD activity and treeing inception in cables, the behaviour of PD in paper-oil insulation subjected to mixed AC+DC waveforms, PD detection in HVDC cables. He is co-author of about 250 scientific papers and 15 international patents, co-founder of the University spin-off Techimp and is active in IEEE (DEIS Adcom member 2010-2016, DEIS Education committee chair from 2010, DEIS Italy Chapter President, member of insulating materials endurance WG), CIGRE (Italian national representative 2004-2008, convener of WG D1.43 and D1.74 both regarding electrical insulation under repetitive voltage surges), and IEC TC 2 MT 10.
