Biography

Roger Luis Brito Zamparette, born in 1992, is from Sao Luis, Maranhao, Brazil. He received his BSc degree in Electrical Engineering at the State University of Santa Catarina, in 2014, presenting the thesis entitled "Automation, Modeling and Control with an Alternative Interface of a Wheelchair". During his studies, he did an internship at WEG Drives and Controls, Jaragua do Sul, Brazil. He continued his electrical engineering MSc studies at the Federal University of Rio Grande do Sul, graduating in 2017. His master's thesis is entitled "A 90% Efficiency 60 mW MPPT Switched Capacitor DC - DC Converter for Photovoltaic Energy Harvesting Aiming for IoT Applications". He joined the Electronic Instrumentation Laboratory of the Delft University of Technology in December of 2018.
