Gerhard Chroust (born April 23, 1941) is an Austrian systems scientist and Professor Emeritus for Systems Engineering and Automation at the Johannes Kepler University of Linz, Austria. Chroust is an authority on formal definition of  programming languages, system development processes, software quality standards and process assessment, and impacts of cultural differences on system development.

Current key research areas are: Human Aspects and Cultural Differences in System Development, Systemic Aspects of System Development and Disaster Management, and Representation and Enactment of Software Process Models

He started to study Communications-electronics in 1959 and received a Diplomingenieur ('M.Sc.') from the Vienna University of Technology in 1964, a M.Sc. from the University of Pennsylvania in 1965, and a PhD. from the Vienna University of Technology in 1974.

From 1966 to 1991 Chroust worked at the IBM Laboratory Vienna in the fields of Formal Definition of  Programming Languages, Compiler Development, Modeling of Software Development Processes and Microprogramming.

During these years he also became Lecturer for Microprogramming at the Johannes Kepler University Linz and the Technical University Vienna in 1975.  In 1980 he was awarded the title of Assistant Professor in Computer Science, and lectured “Microprogramming”, "Dataflow Mechanisms", and later "Software Development Processes" at the Johannes Kepler University Linz, at the University of Klagenfurt, and at the Technical University of Vienna. From 1992 until 2007 he was tenured Professor for 'Systems Engineering and Automation' at the Kepler University of Linz and Head of the Department (in 2004 transformed into an Institute) of Systems Engineering and Automation. He has been a Professor Emeritus since 2007 and is primarily engaged in project work related to systemic aspects of disaster management.
