Engineering leadership and entrepreneurial vision at the intersection of nuclear, energy, and business innovation. Building companies and the low-carbon future.
The short version.
I work at the intersection of nuclear engineering, energy systems, and business. My career blends deep technical expertise with entrepreneurial drive — building companies, filing patents, and delivering in some of the most demanding regulated environments in the world.
As a Design Engineer at a UK nuclear licensed site, I support frontline engineering and technical assurance for operational facilities, from nuclear materials management to remediation of ageing assets. In parallel, I run businesses in the UK and Greece — Instacar Ltd in the UK used-car market and G.I. Security S.A. in the Greek security products sector.
I hold five patents, have published in peer-reviewed journals, and represented Greece at the World Robot Olympiad on three continents. My academic credentials span four degrees including a PhD, and my research focuses on hydrogen technologies and nuclear energy as enablers of the low-carbon transition.
Whether engineering a nuclear facility, growing a business, or filing a patent — I believe innovation must serve both people and planet.
