About Me

I am an AI Researcher at LG Electronics Silicon Valley Emerging Technology, CTO Office, concurrently completing my M.S. Computer Science - AI at University of Southern California (USC). I obtained my B.S. in Computer Science and Engineering at University of California - Irvine (UCI), conducting research under Aditi Majumder. I was also an SDE Intern at OptumRX - UnitedHealthCare.

My research interests are in 3D Reconstruction and Segmentation. Currently, I’m investigating the following topics:

  • Hyperrealistic 3D Reconstruction from Sparse Images In-the-Wild
  • Tiny Interactable 3D Segmentation in Noisy, Low-Resolution Scenes
  • Efficient Visual Models

Research Keywords

Computer Vision, 3D Reconstruction, Scene Understanding, Foundational AI, Edge AI, Medical AI
