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.
