Welcome to Big Data Systems and Applications Lab

In Big Data Systems & Applications Lab at UNIST, we investigate programmability, scalability, fault tolerance, manageability, and performance of big data systems (distributed/parallel systems). Also we are interested in applications of big data systems, and study big data mining and analytics in areas ranging from bioinformatics, medical informatics, to social science and economics. Besides these areas, we collaborate with Stanford MobiSocial Group to study innovative platform for Internet of Things. See the Research Page for the (partial) list of research projects. Contact Prof Seo for the full list of research projects.

Research Topics include:
  • Large-scale data processing systems -- novel systems as well as improve and extend existing systems such as Hadoop, Spark, Presto, etc.
  • Graph analytic systems and algorithms
  • Large-scale data mining and analysis with Machine Learning
  • Big data visualization

  • We have new group members -- Bongki Cho from PNU and Junghoon Kim from KAIST (from December). They will work as a researcher. Please welcome them!
  • Prof Seo has been awarded the research grant for Young Researchers by National Research Foundation of Korea (NRF). Our research on distributed system for large-scale machine learning will be funded by NRF from 2016 to 2019.
  •  We have openings for Undergrad(intern)/Master/PhD students and postdocs. If you have strong background in systems and/or big data mining, please contact Professor Seo (jseo at unist.ac.kr).
