Profile

About & Research

Building learning systems that reason about dynamic worlds and remain dependable when conditions change.

I am a Ph.D. student at the KAIST Cho Chun Shik Graduate School of Mobility, where I study world models and autonomous driving. Before joining KAIST, I worked as a Perception Algorithm Engineer on the Scene Team at WeRide, focusing on traffic-light perception and perception-based monitoring of operational design domain (ODD) conditions.

I received an M.S. in Cyberspace Security from the School of Cyber Science and Technology at Beihang University (BUAA) in 2024 and a B.S. in Information Security from the same school in 2021. My current interests span world models, autonomous driving, embodied AI, and trustworthy machine learning.

Experience

End-to-end perception development, from data and learning systems to production-facing C++ components.

Perception Algorithm Engineer · Scene TeamWeRide · Perception Team
  • Developed traffic-light detection and recognition systems and perception models for monitoring ODD-relevant conditions, including weather, sensor operating status, and road-surface conditions. The resulting signals supported decisions on whether prevailing conditions permitted Robotaxi operation within the defined ODD.
  • Designed and implemented methods for image classification, state classification, 2D object detection, and anomaly detection, contributing across the complete development lifecycle: data management, model training, preprocessing, post-processing, and C++ fallback components.
Perception Algorithm InternWeRide
  • Designed a human-in-the-loop framework for semi-automated annotation. At each iteration, a randomly sampled subset of the data pool was manually annotated to estimate the model's precision–recall curve and calibrate confidence thresholds against target precision and recall requirements.
  • Added pseudo-labels that satisfied the calibrated thresholds to the training set, retrained the model, and repeated the cycle. The framework met its design objectives and increased annotation throughput by more than 5×.

  • Contributed to the development and optimization of deep-learning models for wafer defect detection.
