Tamás Frey

After graduating, he worked as an assistant professor at the Department of Mathematics at the Budapest University of Technology (BME). From 1951, he was a post-graduate student at the Institute of Applied Mathematics of the Hungarian Academy of Sciences. In 1956, he was a candidate. During the construction of the first Hungarian electronic computer, the M-3, he was a member of the Cybernetics Research Group of the Hungarian Academy of Sciences (KKCS), then from 1962, he was the head of the department of the successor institution, the Hungarian Academy of Sciences Computer Center (SZK), and from 1963, its director. In 1968, he defended his academic (MTA) doctoral dissertation entitled “Automata, algorithms, their optimization and approximation”, which was the first Hungarian doctoral dissertation related to the foundations of computer science. He also researched the application possibilities of mathematics and contributed to the development of computer solutions for the reconstruction of the Elizabeth Bridge.

In 1969, he became a university professor at the Department of Mathematics of the Faculty of Electrical Engineering (VIK) of the Hungarian University of Technology (BME), and also the chief scientific advisor of the Computer Science and Automation Research Institute (SZTAKI) of the Hungarian Academy of Sciences. (In the 1959/60 academic year, he was the first lecturer of the elective course Theoretical and Practical Issues of Computer Programming at BME, which was introduced at that time.)

His main research areas: simulation of biological signals, medical diagnostic problems, programming theory, mathematical linguistics. His successful medical topics: a mathematical analysis system for clinical-diagnostic purposes of electromyographic activities, a new method for the analysis of quasi-stationary bioelectrical processes, a mathematical model system of electrical activities of the central nervous system, machine clinical diagnostics. His patent: a curve scanner, which is particularly suitable for processing biological signals.

Könyvei mellett (magyar és idegen nyelvű) publikációinak száma több mint száz. Tagja volt az MTA Műszaki Tudományok Osztálya Automatizálási és Számítástechnikai Bizottságának és az NJSZT-nek. Szerkesztőbizottsági tagja a Studia Scientiarum Mathematicarum Hungaricae és az Acta Cybernetica c. lapoknak.
Szerzőtársával, Szelezsán Jánossal együtt szerkesztette a Számítástechnika és a Matematikai kibernetika – e témakörökben elsőként megjelent - értelmező szótárakat (Akadémia Kiadó, Budapest, mindkettő: 1973.).
