I am an assistant professor at Nara Institute of Science and Technology (NAIST), Japan. I worked for Hitachi Ltd. as a full-time software engineer for two years before spending three years as a research fellow of the Japan Society for the Promotion of Science. I received my Ph.D. degree in engineering from Wakayama University in 2020. After this, I was a post-doc under SENSOR (SENsible SOftware Refactoring) project led by Yasutaka Kamei and Gabriele Bavota.
My research interests include empirical software engineering, specifically the analysis of software bugs, testing, refactoring, and release. In recent years, I have focused on utilizing trace logs generated during test exercises using dynamic analysis. These generated traces can improve Just-in-time bug predictions and automatic refactoring tools. Also, many of my projects involve foreign researchers from Canada, Switzerland, and South Korea, etc.
