Professional Summary

Fourth-year Ph.D. candidate at Show Lab, National University of Singapore, advised by Prof. Mike Zheng Shou. Research focuses on LLM agents, multimodal understanding, and continual / compatible learning. Four first-author or co-first-author conference papers at ICLR, IJCAI, AAAI, and ECCV; three production agent systems delivered at TikTok Shop within five months. Currently working on Agentic Search at TikTok Search.

Experience

  • 2026 - Present

    Singapore

    AI Research Intern
    TikTok Search (ByteDance)
    Agentic Search and Tako: scenario-aware agent policies, evidence-driven system iteration, and ongoing model-training design.
    • Led Auto-Skill policy iteration: failure diagnosis, bounded strategy changes, versioned experiments, and evaluation of the delivered search experience.
    • Developed scenario-specific prompts while preserving shared planning and response contracts.
    • Ongoing data work - faithful trajectories that distinguish model-visible evidence, agent actions, runtime repairs, and final rendered outcomes.
    • Ongoing training and evaluation design - compare SFT, reinforcement learning, and on-policy distillation; evaluate agent behavior and product quality separately.
  • 2026 - 2026

    Singapore

    AI Research Intern
    TikTok Shop (ByteDance)
    Led FIRE, EvoA, and APA from design to production within five months, working with business and infrastructure partners on integration and rollout.
    • FIRE - designed a reusable skill-based agent harness with semantic routing, progressive context loading, and governed tool execution for e-commerce workflows.
    • EvoA - built an autonomous model-iteration loop combining diagnosis, pilot experiments, validation gates, and reusable experiment memory; reduced the human audit rate by approximately 4.6% relative in a controlled online experiment.
    • APA - built evidence-driven risk discovery using joint content / product signals, scoped expansion, deduplication, and provenance-aware review; expanded candidate throughput approximately 17-fold in workflow measurements.
    • Owned architecture, implementation, experimentation, evaluation, and cross-team integration.
  • 2023 - Present

    Singapore

    Ph.D. Researcher
    Show Lab, National University of Singapore
    Research on grounded agent recovery, reliable supervision, evolving state, and continual model adaptation.
    • ReGRPO - grounded reflection and corrective tool use; accepted at ECCV 2026.
    • SGRC, StateTrackBench, and PathComp - first-author submissions under review at ICLR 2027.
    • POU-OPD - first-author submission under review at AAAI.
    • Four first-author or co-first-author conference papers across ICLR, IJCAI, AAAI, and ECCV; TaCA is an additional preprint.
