Strategic leader at the frontier of science, innovation, and deeptech for societal challenges. From fusion energy to philanthropic capital deployment and deeptech ecosystem, I build systems that enable bold, high-impact initiatives to thrive. TED speaker and published author with a history of public engagement at the highest levels, I have published more than 250 scientific articles, I authored the book ‘Energy Chronicles’, and contributed to three other books. I am regularly featured in major media on topics related to deep tech, energy and climate. In October 2025, with 55 other runners I became holder of the Guinness record for the World’s deepest marathon.
