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.
