Hi, I'm Hajun Jang 👋

Mechanical Engineering undergrad @ SUNY Korea · MEIC Lab

I work on data-driven physics modeling — teaching machines to discover the governing equations behind physical systems from data. My long-term goal is physics-informed modeling as a foundation for robust, real-world robotics.

🔬 Research Interests

  • Data-driven equation discovery — SINDy, DMD, weak/integral-form methods (WSINDy); model discovery under partial observation & noise
  • 3D reconstruction — Structure-from-Motion, 3D Gaussian Splatting, sparse-view reconstruction
  • Physics-informed ML & PHM — neural operators (FNO), prognostics, remaining-useful-life prediction

🚧 Currently Working On

  • Adaptation–detection trade-offs in data-driven equation discovery under partial observation
  • On-device capture guidance for SfM + 3DGS reconstruction
  • Interpretability of physics neural operators

📌 Selected Projects

Project Description
DMD-SINDy DMD + SINDy for compact, stable governing-equation discovery from vortex-shedding flows · KSME 2026
Bearing-RUL-OrderTransformer Speed-robust bearing RUL: order tracking + time-gap-aware Transformer + causal EOL smoothing, leak-free eval · PHM Korea 2026
