#Biography
I am a second-year M.Sc. student at Osaka University, Japan and am project researcher at SANKEN, Osaka University. In a nutshell, I am interested in data mining of time series data. Specifically, my research topics are (RQ1) Stream processing and (RQ2) Causality. I am fortunate to be advised by Prof. Yasushi Sakurai and Prof. Yasuko Matsubara at SANKEN. I recieved my B.Sc. degree from Osaka University advised by Prof. Makoto Onizuka in March, 2023. I am participating in Humanware Innovation Program to deepen my knowledge in other fields.
