A theoretical physicist by training, he worked as a programmer at the Mathematisch Centrum (Amsterdam) from 1952 to 1962. He was a professor of mathematics at the Eindhoven University of Technology (1962–1984) and a research fellow at the Burroughs Corporation (1973–1984).
Carl Chang (computer scientist) Carl Kochao Chang () is Professor of Computer Science, Professor of Human Computer Interaction and Director of Software Engineering Laboratory in the Department of Computer Science at Iowa State University where he served as its department chair from 2002-2013. He received a PhD in computer science from Northwestern University. He worked for GTE Automatic Electric and Bell Laboratories before joining the University of Illinois at Chicago in 1984, where he directed the International Center for Software Engineering. He served as Professor and Director for the Institute for Mobile, Pervasive, and Agile Computing Technologies (IMPACT) at Auburn University from 2001–2002, before moving to Iowa State University in July 2002. Chang was the 2004 IEEE Computer Society president. Previously he served as the Editor-in-Chief for IEEE Software (1991–1994) and Editor-in-Chief for IEEE Computer (2007–2010). He spearheaded the Computing Curricula 2001 (CC2001) project jointly sponsored by the IEEE Computer Society, the ACM, and the National Science Foundation. He is a Life Fellow of IEEE, a Fellow of AAAS, and a member and an officer of the European Academy of Sciences. He received the 2000 IEEE Third Millennium Medal, the 2006 Bulgaria Academy of Sciences Marin Drinov Medal, and the 2012 IEEE Computer Society Richard E. Merwin Medal. As a three times winner of IBM Faculty Award, Chang’s research interests include software engineering, human computer interaction and digital health. He is the founder of Situation Analytics based on his Situ theoretical framework. He is the recipient of the 2014 Overseas Outstanding Contribution Award from China Computer Federation (CCF 中国计算机学会) as well as the 2014 Distinguished Alumnus by the National Central University in Taiwan (中央大學－台灣)。
