Makoto Onizuka
As represented by the phrase “Data is the new oil”, it is expected to make social impact by discovering knowledge from Big data. In the real world, since databases are managed independently in multiple companies, it is important to research and develop technology that integrates and analyzes those heterogeneous databases. We are engaged in research on a technical field of distributed/parallel data analysis, efficient graph analysis algorithms, and exploratory data mining. We publish our papers at top conferences, such as VLDB, SIGMOD, ICDE, EDBT, KDD, AAAI and also collaborate with major industries for practical research.

Languages are so familiar with us; we read, speak, and write text daily. But at the same time, languages are so mysterious. We don’t know how we process them to think and communicate. I’m working on natural language processing with the dream of unveiling this secret hidden in our brains.

The cognitive capacity of Homo sapiens is inherently limited. Research serves as a direct means to expand these boundaries, and AI emerges as the ultimate resolution to this constraint. Investigating AI parallels a hiker traversing two divergent paths simultaneously. It is an honor to be part of this journey.
