Research:

WE are working on software engineering issues of building software systems that effectively utilize various resources in emerging environments such as the Web, clouds, Internet of Things (IoT), and Cyber-Physical Systems (CPS). We especially focus on making software systems adaptable to changing needs and conditions in highly dynamic environments, and allowing end users to participate in the evolution of the software

Research Areas

  • Software engineering for dynamic environments
    • Adaptive and evolvable software design
    • Software design and testing for DevOps and continuous integration
    • Knowledge-based software engineering
    • End-user software engineering
  • Services computing
    • Task-oriented service provision for IoT and CPS environments
    • Service composition/mashups
    • Service-oriented architecture
  • Web applications
    • Web application testing
    • Semantic and mobile Web applications
    • Web-based information modeling and management

Detailed Research Topics

The Web: A Platform for Software Engineering

The Web_ a platform for software engineering

  • Provides repositories for searching software services
  • Provides a medium for deploying software as services
  • Supports protocols to access software services
  • Supports an environment to dynamically compose (assemble or synthesize) applications
