Pree is a Full Professor of Computer Science at the University of Salzburg, Austria since 2002.

His C. Doppler Laboratory[1] Embedded Software Systems (2007–2014) in cooperation with AVL List focused on real-time software in automobiles and automation systems.

The research results are further developed into products by Chrona and are deployed in Daimler's next generation of electric vehicles since 2019/20.

Pioneering work has been done in the field of autonomously driving trains on open tracks since 2008: the Austrian Klima- und Energie-Fonds supported the autoBAHN project, so that a pilot system could be implemented on the Stern&Hafferl line between Vorchdorf and Gmunden in 2008–2013.

[2] Pree initiated Go4IT in 2017 (start of a bachelor's degree in computer science at high school): high school students can attend introductory courses in computer science at the University of Salzburg from 9th grade onwards.
