I am an associate professor at Osaka University, Japan. My research focuses on spatio-temporal/graph data management/analysis, trustworthy AI, and applied data science to other fields such as chemical and medical science.
I obtained my PhD degree (Information Science) from Osaka University in 2014.
Open positions for highly motivated Ph.D course students.
