He obtained his engineer's degree in electrical engineering and his engineering-teacher's degree from the Technical University of Budapest in 1971. He was taken in by the Physics Department of the same institution on a science grant. His fields of scientific interest included the physics of solid bodies and the quantum mechanical modelling of metal surfaces. He was the first in Hungary to explore the theoretical background of the Scanning Tunnel Microscope (STM). His PhD thesis summarised his own theoretical results in this field. He has always considered it crucially important for the (electrical) engineers of the twenty-first century to adopt the approach and knowledge base of modern physics that would enable them to successfully solve technical and development problems emerging in the rapidly developing field of electrical engineering. Pseudo-science enjoys considerable popularity today, which does not leave engineering undergraduates unaffected; based on his personal experience as a lecturer, László Orosz began to fight against pseudo-science among his own students fifteen years ago.
