    CV

    I am a Brazilian-Italian with experience in computer engineering and emphasis on programmable systems. As an undergraduate student, I worked in the project of the first Brazilian nanosatellite, the NanoSatC-BR1. My main task was the project of the embedded software of the satellite’s onboard computer. My bachelor degree thesis focused on the analysis of single event effects on fault-tolerant memory architectures at circuit level by using a SPICE simulator. My master degree was focused on the characterization of programmable mixed-signal system-on-chip devices and evaluation of fault-tolerant techniques under radiation. The main case-study device was the Microsemi SmartFusion. My Ph.D. focused on analyzing the reliability and performance trade-offs on programmable system-on-chip devices under radiation. The main case-study device was the Xilinx Zynq-7000. Some side projects include: project and development of one of the payloads of the second Brazilian nanosatellite, the NanoSatC-BR2; project and development of hardware accelerators for Xilinx devices using the Vivado High-Level Synthesis tool; project and development of hardware with communication interfaces, such as UART, I2C, SPI, Gigabit Ethernet, SERDES, etc.; development of a fault-tolerant manager core to perform dynamic partial reconfiguration in Xilinx devices; development of a fault injection platform for Xilinx devices; project, development, and evaluation of fault-tolerant techniques for FPGAs, System-on-Chips, and Microprocessors; realization of radiation experiments in the several research institutes where I have collaboration works, such as the Universidade de São Paulo (USP), European Organization for Nuclear Research (CERN), National Research Nuclear University (MEPhI), Los Alamos National Laboratory (LANL), and Rutherford Appleton Laboratory (RAL-ISIS). Furthermore, I am a quick and self-learner and I can handle well working under pressure and with short deadlines.
