About me

I received Ph.D. degree in the Department of Computer Science at Virginia Tech. I was a member of the Software Innovations Lab, advised by Prof. Eli Tilevich. My research interests are Systems end of Software Engineering. Previously, I worked in Robotics Research at KIST and access R&D team at SK telesys. And I completed my masters degree from POSTECH, under the supervision of Prof. Hwangjun Song.

Research Interests

  • Refactoring/Optimizing Distributed Systems, Software Engineering, Web-based Systems, Apps of Machine learning, Software Security, Networking
  • Research Statement
  • In my dissertation, I studied refactoring tools for distributed apps in the purpose of facilitating re-engineering of the distributed apps. My approach has a novelty in that it creates a centralized variant of the distributed apps first, then applies perfective and architectural changes of the original distributed apps. My idea solved non-trivial tasks for evolving distributed apps: localizing bugs, optimizing distribution granularity, and replicating a subset of distributed apps into different machines for enabling edge-based/centralized computings. I improved the latest software engineering’s latest ideas such as fuzzing/checkpointing the HTTP executions (RESTful APIs) and declarative program analysis with the z3 constraints solver, and data replication techniques (i.g. relaxed consistency models). My dissertation research was presented in WWW 2020, ICWE 19, SANER 20, and ICWE 21 with the Best Paper award.
