Driven, structured and technically-minded; I have a strong background in space-applied electronics and control systems from a multidisciplinary education and varied work experiences in prominent space companies and agencies. Proven aptitude for working in international teams, in highly-technical positions and with customers; I have excellent social, engineering and presentation skills.
Lead designer for the Cube#0 payload which has been installed on-board the International Space Station in June 2018.
Developed a digital PWM-based control method for the S3R converter which highly mitigates variable frequency issues.
Developed a digital shunt current limitation method for the S3R which avoids commonly required oversizing of the MOSFETs.
Developed at the time Thales Alenia Space’s fastest analog closed-loop DC-DC switching converter (switching at 6.5 MHz).
Bachelor’s and Master’s degree both achieved with the “magna cum laude” honor.
Author on two published papers about power electronics, several more unpublished on ResearchGate.
