I'm a PhD graduate from Zhejiang University, working at the intersection of AI infrastructure and computer vision. I contribute to large-scale training frameworks (VeOmni, verl) while publishing research at top-tier venues (NeurIPS, ICCV, IJCAI, ECAI, IEEE TMI).

My research spans distributed training systems, vision-language models, and computational imaging.

I'm a contributor to open-source AI training frameworks, including VeOmni (model-centric distributed training recipe zoo) and verl / verl-omni (multimodal RL post-training frameworks).

Selected Contributions:

• VeOmni: Deterministic mapping cycles for dataset mixtures, HSDP all-reduce control, and Qwen3-VL FSDP2 compilation support
• verl-omni: Refill incomplete diffusion rollout groups, batched PickScore inference, and preserve diffusion asynchronous semantics

Research directions:

• Parallelism & memory optimization — packed sequence packing, ChunkMBS, FSDP2/hsdp integration
• Training-time validation — distributed metric aggregation and evaluation pipeline
• Hardware portability — NPU training enablement and cross-platform validation
• Multimodal reward engineering — batched reward inference and reward model integration
• Rollout & training pipeline — async semantics, rollout-train consistency, group management
• Efficient post-training — LoRA/FSDP for VLMs, distributed reward handling
