• Jan 2020 – Sep 2020, Undergraduate Student Researcher, AI & SE Lab (Advisor: Prof. Duksan Ryu)

  • I learned systematic research methods from him.
  • Even after I left his lab, I continue to be guided by his research on Software Defect Prediction (SDP) and Bug Report Prediction among software engineering research.

• Nov 2018 - Dec 2019, Undergraduate Student Researcher, Systems & Software Engineering Lab (Advisor: Prof. Suntae Kim)

  • He talked to me about invaluable stories such as the research life, philosophy, and so on.
  • He has a distinctive research method with a balance between engineering and philosophy. I learned from him how to explore "why this research is needed".
