Biography
Harald Søndergaard is a Professor in the School of Computing and Information Systems at the University of Melbourne. His primary research areas are software reliability and security, program analysis, software verification, and declarative programming languages.
Harald received an MSc in Computer Science in 1987 and a PhD in 1989, both from the University of Copenhagen. He has been a member of academic staff at the University of Melbourne since 1990, serving as Deputy Head of Department in 2002-2003, as Associate Dean (Learning) in the Engineering Faculty from November 2001 to June 2006, and as Assistant Dean (Teaching Quality) in the Melbourne School of Engineering from July 2007 to June 2009.
Harald has received national awards for teaching excellence (the inaugural CORE Teaching Award 2007 and a citation from the Australian Learning and Teaching Council in the same year) in addition to many local university awards. He has been a member of the University's Teaching and Learning Development Committee for more than a decade and he publishes regularly on engineering and computer science education.
