Michael Schrefl completed his degree in computer science at the Vienna University of Technology (TU) in 1983. From 1983 to 1984, he studied Artificial Intelligence at Vanderbilt University, Nashville, TN, on Fulbright scholarship. He then was as a university assistant at the Institute for Applied Computer Science - Databases and Artificial Intelligence (DBAI) at the Vienna University of Technology from 1985 to 1992. As part of his dissertation work, he spent a one-year research stay at the Gesellschaft für Mathematik und Datenverarbeitung (GMD, today: Fraunhofer-Gesellschaft) in 1987/88 and obtained his doctorate in technical sciences at the Vienna University of Technology in 1988. In 1991, he qualified as a professor of applied computer science at the Vienna University of Technology ("Habilitation") and was immediately appointed full professor of business informatics at the Johannes Kepler University (JKU) Linz.
In 1998, he was appointed Professor of Computer & Information Science at the University of South Australia (UniSA), Adelaide, where he worked full-time from 1998 to 2000. Since his return to the JKU Linz in 2000, he has maintained close ties with UniSA through research cooperation and research visits. His research projects have been funded by FWF (Austrian Science Fund), FFG (Austrian Research Promotion Agency), ARC (Australian Research Council), EU Horizon 2020 (EU funding program for research and innovation). He has over 150 peer-reviewed publications in the field of Data & Knowledge Engineering in international journals and proceedings of international conferences.
Michael Schrefl currently heads the Institute for Business Informatics - Data & Knowledge Engineering at the Johannes Kepler University Linz with current collaborative research projects on the use of artificial intelligence in aviation funded by the EU Horizon Europe research program.
