Harald Gall is Dean of the Faculty of Business, Economics and Informatics and Professor of Software Engineering at the University of Zurich, Switzerland (UZH).
Before joining UZH in 2004, he was associate professor at the Technical University of Vienna, Austria, in Distributed Systems (TUV). He studied at TUV and holds a PhD (Dr. techn.) and master's degree (Dipl.-Ing.) in Informatics.
His research interests are in evidence-based software engineering with focus on quality in software products and processes. This focuses on long-term software evolution, software architectures, software quality analysis, data mining of software repositories, cloud-based software development, and empirical software engineering.
He is probably best known for his work on software evolution analysis and mining software archives. Since 1997 he has worked on devising ways in which mining these repositories can help to better understand software development, to devise predictions about quality attributes, and to exploit this knowledge in software analysis tools such as Evolizer, http://www.evolizer.org or SOFAS, http://seal.ifi.uzh.ch/sofas
He was associate editor of IEEE's Transactions on Software Engineering and currently is associated editor of Springer's Empirical Software Engineering Journal and Springer's Computing Journal. He was the program chair of the two flagship conferences in the field of software engineering: ICSE in 2011 and ESEC/FSE in 2005.
