Work

  • 2025.01 - Present
    Research Scientist
    Alibaba-NTU Global e-Sustainability CorpLab (ANGEL)
    Applied generative AI research focused on domain-specific LLMs for clinical applications, agentic reasoning over knowledge graphs, and memory-efficient inference.
    • Architected a multi-turn dialogue system that emulates real-world medical consultations and diagnostic workflows.
    • Spearheaded large-scale dataset construction from the MIMIC clinical database for SFT and conversational evaluation.
    • Engineered KAG and GraphRAG frameworks for the medical domain, validated against the MedQA benchmark.
    • Improved serving throughput and reduced latency using FlashAttention, SDPA, and vLLM.
  • 2020.01 - 2025.01
    Research Engineer II
    Alibaba-NTU Singapore Joint Research Institute
    3D computer vision and generative AI research, with production integrations into Alibaba Video products.
    • Architected end-to-end pipelines for 3D indoor scene synthesis and point cloud generation in PyTorch, automating 3D modeling workflows in Python and Blender.
    • Partnered with the Alibaba Video team to deploy models powering automated video captioning, gaming recaps, and intelligent video enhancement.
  • 2017.02 - 2018.06
    Senior Engineer
    Skyworks Global Pte. Ltd.
    Silicon controller design for 2G/3G/4G power amplifiers and SOI switch modules.
    • Directed silicon controller design from specification through circuit realization and ATE, achieving a 100% first-silicon success rate across all Si/SOI die designs.
    • Developed the SOI Band Select Switch Module with custom digital logic, level shifters, and ESD networks, driving process migration to volume production.
  • 2012.06 - 2020.01
    Senior Engineer
    Marvell Asia Pte. Ltd.
    Digital and software architecture for high-speed, low-power storage ICs.
