LEE HOJUN

Mechanical Engineering undergraduate interested in physics-informed and data-driven modeling for mechanical systems.

I use GitHub to organize undergraduate projects and self-study work before graduate research. My current focus is on applying machine learning, simulation, and physical modeling to mechanical system analysis, diagnosis, and control.

Research Interests

  • Physics-Informed Machine Learning
  • Mechanical System Modeling and Vibration
  • Data-driven Fault Diagnosis and PHM
  • Simulation-based Analysis and Control
