John Mylopoulos (born 12 July 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.[1][2]


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."[3]

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.

In 1986, Mylopoulos was elected President of the Greek Community of Toronto. He served for 2 years until 1988.

Mylopoulos was awarded the Peter P. Chen Award for outstanding contributions to the field of conceptual modeling in 2010. In 2012 he also received an 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.".[4]


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."[5] Borgida et al. (2009) summarized, that Mylopoulos made four mayor contributions in these fields:

  • TORUS: Natural-language access to databases, which required the representation of the semantics of the data, and hence first led us to conceptual models of relational tables using semantic networks.
  • TAXIS: Programming language for data-intensive applications which supported classes of objects, transactions, constraints, exceptions and workflows, all orthogonally organized in sub-class hierarchies with property inheritance.
  • TELOS: Representation language for knowledge of many different kinds of software engineering stakeholders, including application domain and development domain, which exploited meta-classes, and treated properties as object
  • TROPOS: Applying the ideas of early requirements (goal orientation, agent dependence) to the entire range of software development, and expanding its scope to many topics, including security and evolution.
