Areas of specialization Software verification and analysis
Laboratory/research office Software Verification and Analysis Laboratory
As computers are more widely utilized, defects of the software come to have great influence on our daily life. Software that seems to have no defect may sometimes cause a trouble when several rare events occur simultaneously. In this laboratory, we study methodologies for verifying the correctness of software as well as specification languages for software system suitable for logical verification.
Current research topics Model checking of programs with language-based access control Access control models for XML databases
