Research

My research areas are system software, operating systems and virtual machine technology. Current computer systems are still running with the lack of reliability stemming from not only the complexity of system software but also from failure-prone hardware devices. To make computer systems more powerful and reliable, we are now exploring system software technology in the following research topics;
  • System Software Technology for Taming Software Bugs
    • The complexity of system software disables us to completely eliminate bugs and security holes in the system. Also, short development time prevents developers from adequately conducting software tests. We are developing "bug-conscious" software technology, which elegantly tames buggy software systems to achieve high reliable services.
  • System Software Technology for Gracefully Handling Hardware-Failures
    • Common hardware devices often fail due to their complexity. Some failures silently corrupt parts of data preserved in the device and exhibit transient performance problem, resulting in the decrease of reliability of the system. We are focusing on these failures because common hardware devices are widely used in commercial computing environments like Google web systems and data centers. Our goal is to develop system software technology to deal with hardware failure.
  • Novel Resource Management Techonology
    • Innovative resource management policies must continue to be developed to satisfy the needs of emerging applications and everchanging computing environment such as cloud computing and multi-core architectures. We are exploring mechanisms to achieve novel resource management on operating systems and virtual machine monitors.
