Timothy Christian Lethbridge (born 1963) is a British/Canadian computer scientist and Professor of Computer Science and Software Engineering at University of Ottawa, known for his contributions in the fields of software engineering, knowledge management [2] and computer animation, and the development of Umple. [3]



Born in London in 1963, Lethbridge grew up in Denmead and attended St John's College in Portsmouth [4] until he immigrated with his family to Canada in 1975. [5] He received his BSc in 1985 and his MSc in 1987 in Computer Science from the University of New Brunswick. In 1994, he received his PhD in Computer Science and Artificial Intelligence from the University of Ottawa under supervision of Douglas Skuce for a thesis about tools for knowledge management, [6] entitled "Practical Techniques for Organizing and Measuring Knowledge." [1]

In 1983, still studying, he started working as programmer and analyst for the Government of New Brunswick, where he assisted in the development of software for statistics, health insurance programs, and management information applications. At the university he also taught courses in Fortran programming and Interactive Computing. After graduation in 1987 he became researcher at the Bell-Northern Research, where he developed software for Computer Aided Design applications. From 1990 to 1995 he worked as consultant in multiple research projects.

In 1994 Lethbridge started his academic career at the Department of Computer Science of the University of Ottawa as Assistant Professor, in 2001 Associate Professor, and since 2005 Professor of Computer Science and Software Engineering at the University of Ottawa. [7] He specializes in "Human Computer Interaction, Software Modeling, UML, Object Oriented Design, Software Engineering Education". [8]


Lethbridge published one textbook and over 100 articles. Books:

Software engineering is an engineering-style system of software development. A software engineer is a person who applies the principles of software engineering to design, develop, maintain, test, and evaluate computer software. The term programmer is sometimes used as a synonym, but may also lack connotations of engineering education or skills.

The following outline is provided as an overview of and topical guide to software engineering:

The World Wide Web has become a major delivery platform for a variety of complex and sophisticated enterprise applications in several domains. In addition to their inherent multifaceted functionality, these Web applications exhibit complex behaviour and place some unique demands on their usability, performance, security, and ability to grow and evolve. However, a vast majority of these applications continue to be developed in an ad hoc way, contributing to problems of usability, maintainability, quality and reliability. While Web development can benefit from established practices from other related disciplines, it has certain distinguishing characteristics that demand special considerations. In recent years, there have been developments towards addressing these considerations.

StarUML is a software engineering tool for system modeling using the Unified Modeling Language, as well as Systems Modeling Language, and classical modeling notations. It is published by MKLabs and is available on Windows, Linux and MacOS.

Model-driven engineering (MDE) is a software development methodology that focuses on creating and exploiting domain models, which are conceptual models of all the topics related to a specific problem. Hence, it highlights and aims at abstract representations of the knowledge and activities that govern a particular application domain, rather than the computing concepts.
