John P. Mylopoulos (born 1943) is a Greek-Canadian computer scientist, Professor at the University of Toronto, Canada, and at the University of Trento, Italy. He is known for his work in the field of conceptual modeling, specifically the development an agent-oriented software development methodology. called TROPOS.
Born in Greece in 1943, Mylopoulos in 1966 received his Bachelor of Engineering from Brown University. In 1970 he received his PhD from Princeton University under supervision of Theodosios Pavlidis with the thesis, entitled "On the Definition and Recognition of Patterns in Discrete Spaces."
In 1966 he started his academic career as Assistant Professor at the University of Toronto, where he in 1971 he was appointed Professor in Computer Science. In 2009 he was also appointed Professor of Computer Science at the University of Trento.
Mylopoulos was awarded the Peter P. Chen Award for outstanding contributions to the field of conceptual modeling in 2010. In 2012 he also received a Honorary Doctorate from the RWTH Aachen University in recognition of "his excellent and distinctive contributions on the methodology of conceptual modeling as a basis for databases, software technology and artificial intelligence, as well as its interdisciplinary applications.".
Mylopoulos' research interest ranges from information modelling techniques, specifically semantic data models, to knowledge based systems and information system design and to the field of requirements engineering." Borgida et al. (2009) summarized, that Mylopoulos made four mayor contributions in these fields:
