Dr. Stathis Stefanidis is a physicist, an educator, an author and a technology consultant to private companies with a distinguished academic and professional career.
He obtained his BSc in Physics from the Aristotle University of Thessaloniki and an MSc in Nuclear & Particle Physics from the University of Athens before earning a PhD in High-Energy Physics at University College London (UCL). Supported by the Onassis Foundation and the UK Science and Technology Facilities Council (STFC), his doctoral work focused on the ATLAS experiment at CERN, where he contributed to the discovery and analysis of the Higgs boson.

His doctoral research focused on developing algorithms to enhance detector performance and improve particle identification, cementing his expertise in data analysis, experimental physics, and computational methods.
Alongside research, Dr. Stefanidis has built a reputation as a dedicated educator, with more than 30 years of teaching experience in Physics and Mathematics. At an early stage of his career, he obtained the Qualified Teacher Status (QTS) and since then he has taught and mentored hundreds of students, many of whom have progressed to leading universities including Oxford, Cambridge, Imperial College London, and UCL.
As an author, Dr. Stefanidis has published academic papers in particle physics and data analysis, as well as educational materials and books designed to make complex scientific ideas accessible to wider audiences. His writing reflects his dual passion for cutting-edge science and inspiring future generations of learners.
A member of the Institute of Physics, he continues to contribute to scientific and educational communities, bringing together the precision of research with the clarity of communication.
