Research (recent publications):

Recently published book describes results of my research on reuse, maintenance and XVCL approach:

Jarzabek, S. Effective Software Maintenance and Evolution: Reused-based Approach, Auerbach, CRC Press Taylor and Francis, May 2007 http://www.crcpress.com/shopping_cart/products/product_detail.asp?sku=AU3592   

I am interested in all aspects of software engineering, but especially in design of high-variability software, i.e., software that can be easily evolved and reused. Genericity is a key to high-variability, but conventional methods – OO and component-based – are weak in generic design. I work on providing empirical and analytical evidence for the above claim, and apply a generative technique of XVCL to alleviate the problem. Our approach is practical as it complements, rather than competes with conventional programming methods - we call it mixed-strategy to emphasize this synergistic nature of the approach. Mixed-strategy has been already successfully applied in industrial projects. XVCL is an open source, public domain software (http://xvcl.comp.nus.edu.sg).

Collaboration: An essential part of my research is experimentation and industry collaborations. I have a long-term and fruitful research partnership with ST Electronics (Info-Software Systems) Pte. Ltd. (formerly known as SES Systems Pte. Ltd.).

Research Projects: Our recent projects focus on Web Application engineering for ease of maintainability and for reuse. In those projects, we study the nature of similarity patterns in Web domains and then apply XVCL on top of model-based design, PHP, ASP, JSP, J2EE or .NET to achieve higher degrees of changeability and genericity than it is possible with conventional techniques alone. Another project is on semi-automatic detecting similarity patterns in programs for which we apply string pattern matching, token-based and data mining techniques (see CM/CA technology summary) . Practical applications of methods for detecting software similarities include program analysis for understanding during maintenance, and re-engineering of legacy software into reusable or maintainable representations.

Other research areas I am interested in are software evolution, reverse engineering, design of static program analysis and other software tools, and compiler-compilers (attribute grammars).

Teaching:

Software engineering education is under a lively debate. I am interested in development of software engineering curricula, in particular in software engineering project courses. I believe the role of a university is to teach students fundamental concepts, not over-emphasizing specific technologies that change so fast. Understanding fundamentals creates a reference point and shapes judgment that will help graduates adapt to changes through their careers. It follows that the role of project courses is to teach how to apply proven principles in large-scale team-based software development.  Our CS3215 Software Engineering Project course is described in the CSEE&T paper  [12].

I also teach graduate course on application of product line approach to CS6201 Software Reuse.

Before joining the NUS:

I was a Research Manager of the CSA Research Pte. Ltd. and an Adjunct Senior Lecturer at the NUS (1990-92), Assistant Professor at McMaster University, Canada (1984-1990), a Lecturer at the University of Maiduguri, Nigeria (1982-84) and Research Fellow at the Institute of Computers, Warsaw (1972-82).
