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.

I am engaged in Onizuka laboratory's project on the research and development of data integration systems, taking part in project management and student supervision. My research interests also include information retrieval, textual data management, and spatio-temporal databases.

Research is necessary to create a new and better world. I am trying to generate new ideas and concepts through research activities such as writing papers and social implementation. It gives us great experiences and opportunities. Research is really enjoyable and fantastic.

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.

My research interests are in the areas of data engineering, data mining, artificial intelligence and machine learning. Due to the rapid developments of database and internet technologies, it is possible to manage large volumes of data in high capacity systems. I work on developing of computationally efficient algorithms for large and complex problem.

My current research interest lies at the intersection of computer science, law, and economics, with a particular focus on data economy, data privacy, and computational law.

Ronny Hajoon Ko I am a specially appointed assistant professor at the Graduate School of Information Science and Technology, Osaka University. I research what-if analysis, workload optimization, data security and privacy. I also research signal processing of ion mobility spectrums.

My research interests relate to the Internet of Things, Big Data, machine learning, artificial intelligence and edge computing. Currently, I am working on researching query optimization in relational databases to enhance system performance. I am passionate about leveraging advanced technologies to solve real-world challenges.
