Zoltán Illés

After graduating from university, he began teaching at the Faculty of Natural Sciences (TTK) of ELTE.
From 1987 to 1990, he worked as a software developer at the Nuclear Reactions Laboratory of the Joint Nuclear Research Institute (EAI) in Dubna. His task was to develop measurement control programs for ion irradiation experiments. Here he first encountered real-time systems, which became a defining element of his later work. He completed his PhD thesis in 2001 as a result of the development of a real-time application.

He continued to participate in the work in Dubna after his return home in 1990 until 2006.
He returned to the university in 1990, where he has been working at the Department of Media and Educational Informatics of the Faculty of Informatics (IK) as an associate professor (habilitation in 2018). He participates in the teaching of several subjects - also developing their curricula. He is the subject manager of Computer Systems and Operating Systems. He also leads the English-language training of these subjects. He is a supervisor at the Doctoral School of Informatics at ELTE.

Since 2008, together with Viktoria Bakonyi, Heizlerné has regularly participated in the training of future teachers, including future IT teachers, at the Faculty of Central European Studies of the Konstantin Philosophical University in Nitra. They have also taken part in the research work of the Faculty, collaborated with the faculty's lecturers in several joint projects; their joint publications have also been published. They are also active in an international Slovak-Hungarian joint project (within the framework of the project, they are conducting research related to mobile devices).

His research areas include mobile devices, web systems, embedded systems operating systems, real-time systems measurement and control, and computer science.

In 2016, the NJSZT awarded Mrs. Heizlerné the Tarján Award, shared with Viktoria Bakonyi and Ildiko Psenák, in recognition of their exemplary cross-border cooperation.
