I build code agents for long-horizon tasks, and study how to scale the harness around them, design the agent loop, and train agents with cost-aware RL. I also work on neural parameter generation.

01About

I am a Principal Researcher at Tencent, leading efforts on code agents for long-horizon tasks. I also collaborate closely with Prof. Atlas Wang.

I received my Ph.D. in 2025 from the NUS HPC-AI Lab, advised by Prof. Yang You. During my Ph.D., I was an affiliated member at the University of Toronto with Prof. Konstantinos N. Plataniotis, and a sponsored researcher at Carnegie Mellon University with Prof. Alex Hauptmann. Before that, I received my M.S. in 2020 from MMLab@SIAT, advised by Prof. Yu Qiao and Assoc. Prof. Xiaojiang Peng.

I like simple, strong baselines that reveal how deep learning actually works. Representative work: HY-WU, DnD (NeurIPS 2025), RPG (NeurIPS 2025), p-diff, and PAB (ICLR 2025).

    Long-Horizon Agent Design

    Code agents that reliably finish long-horizon tasks: scaling the harness around the model, designing robust agent loops, and training agents with cost-aware RL.

    • Harness Scaling
    • Agent Loop Design
    • Cost-Aware Agentic RL

    Parameter Generation

    Treating neural network weights as a generative modality: generating, adapting, and composing parameters directly.

    Efficient Generation & Training

    Making model training and diffusion/video generation faster and cheaper, often with simple tricks that drop into existing pipelines.

    Data-Centric AI

    Getting more out of less data: dataset distillation, dataset quantization, and dynamic data pruning for lossless, faster training.
