Professional experience: Lightning Physics research at INPE - Instituto Nacional de Pesquisas Espaciais (2023-); EMC with emphasis on lightning protection, freelancer consultant, lightning studies and research (2021-); Delta Electronics Brasil Ltda. (2020-2021); Embraer S.A. (2017-2020); APTEMC Análises, Pareceres e Treinamento em EMC Ltda. (owner) (2014-2017); Emerson Network Power Ltda. (2000-2014); Ericsson Telecomunicações S.A. (1982-2000). Expert on EMC, working in the area since 1988, with special interest on lightning phenomena and lightning protection. EMC analysis for aircraft (lightning, HIRF (high-intensity radiated fields), EMI, electrostatics). Participation in research activities in collaboration with the atmospheric electricity group at INPE, notably in the lightning measuring campaign on buildings in São Paulo city, with important contribution to the EMC performance of the lightning current measuring setup. Studies, analysis and solutions of problems involving lightning protection and other electromagnetic disturbances, including power quality, LV power distribution, grounding and bonding for equipment, systems and installations, particularly complex electrical installations such as telecom, datacenters and aircraft. Product development, troubleshooting and failure analysis by computer simulations and calculations, as well as field and laboratory measurements. Development and tests of power systems (-48 V DC) and infrastructure equipment for telecom (outdoor cabinets and walk-in shelters), HW design with emphasis on EMC aspects, including PCB layout, shielding, EMI filters and surge protection. Design activities at Ericsson Telecom, Ericsson Energy Systems and Emerson Network Power in Sweden, including a 1-year study at the High Voltage Research Institute at Uppsala University, Sweden (EMC in general, lightning protection, surge tests, cable shielding/transfer impedance). Laboratory and field experience: prototype and certification tests, simulation of failures, specification of test measuring equipment, test setup and test environment, design of auxiliary test devices, characterization of disturbance sources, coupling paths and other interactions, circuit simulation, electromagnetic field simulation. Standardization activities: member of study committees at ABNT; experience in analysis and definitions of technical requirements and standards, for products and electrical/electromagnetic environment. Several activities involve experience in Brazil and in other countries (design, research, tests, troubleshooting etc.). (Fonte: Currículo Lattes)
