With the rapid development of information technology, organizations usually met challenges to utilize emerging technologies: How to properly apply these information technologies? How to develop applications enabled by emerging technologies? And how to protect the security of information applications? As a result, the research group studies means to utilize the emerging technologies, architecture of building applications with the technologies with considering resource utilization efficiency, as well as related cybersecurity issues. Currently, the research group focuses on the following topic:network service-oriented architecture (including fault tolerance network, mobile ad hoc network application and performance analysis on grid computing), network applications (including recommendation system, mobile computing and data mining), artificial intelligence applications (including multi-media systems and human computer interaction), simulation, operation research, information security, and optimization theory.
