I am Associate Professor at Wakayama University, Japan. I am directing Open Source Software Engineering Laboratory (OSSE Lab.) which dedicates our efforts to study Mining Software Repository (MSR) to better understand  open source software products ant its development. Everyday I am enjoying studies with my great students and colleagues! I am also collaborating with workers in software companies, developers in open source communities, and researchers around the world.

This site introduces some of my research activities. Please feel free to contact me if you are interested in them.
