Research

NeuroAI & Neural–Behavior Modeling

Multimodal representations connecting behavior, multi-view video, and neural population activity.

Representation Geometry & Spatial Coding

Auditing topology, geometry, decodability, and out-of-distribution usability in learned spatial representations.

Reliable & Adaptive Multimodal Systems

Diagnosing evaluation failures, routing bottlenecks, and continual-adaptation trade-offs in multimodal models.
Research Experience
Dec. 2025 – present

Columbia University — Liam Paninski Lab

Research Assistant
  • SABLE: cross-view geometry initialization, keypoint-assisted camera calibration, and point-cloud visualization for 3D animal-behavior reconstruction, with controlled ablations over 28-keypoint versus paws-and-nose supervision on Cheese3D.
  • Longitudinal IBL neural-behavior analysis: initial quality control across 60 sessions and POSSM baseline reproduction.
Jun. 2026 – present

Tsinghua University / Qi Zhi Institute — Lu Mi Lab

Research Assistant
  • Initiated Cheap Certificates of Spatial Coding and designed its controlled audit, metric suite, model sweep, and scientific framing.
