01 Profile

Space technology and academic leadership

I connect research, satellite technology development and engineering education, with a focus on CubeSat platforms and the capabilities needed to develop and test space hardware.

At the Instituto Tecnológico de Buenos Aires (ITBA), I work as a researcher and lecturer and co-direct the CubeSat platform project. This activity connects multidisciplinary development with engineering education and the growth of the university’s space technology capabilities.

At CNEA, where I have worked since 2007, I develop hardware for satellite missions and lead projects focused on small-satellite power systems. My background in space photovoltaics, radiation effects, integration and environmental testing supports this broader work in space technology and institutional collaboration.
