I am a Professor in Computer Science at Kyushu University. I lead the String Algorithms and Data Structures group (STRADS) in the Department of Informatics.
Previously I was an Associate Professor in the Department of Informatics at Kyushu University. I also held a research position in the JST PRESTO Project. Earlier on, I was a Research Fellow in the SSP project at Kyushu University, where I also held a Research Associate Professor position. I was a Postdoctoral researcher in the Department of Computer Science at the University of Helsinki.
My current research interests are on Algorithms and Data Structures for Searching, Indexing, Comparing, and Compressing Strings, Labeled Trees and Graphs. Combinatorial properties of Strings are also of my research interest.
