Research

01

Data

Post-training data for foundation models, including supervised fine-tuning, preference optimization, retrieval-augmented data, and synthetic data pipelines. I am also interested in pre-training data scaling laws and data mixture design.

02

Efficiency

Efficient model serving and deployment, especially MoE inference acceleration, expert-load balancing, token dispatch, DeepEP-style communication, and throughput/latency optimization for DeepSeek and Qwen series.

03

Retrieval

Large-scale retrieval and recommendation with semantic identifiers, vector quantization, and generative sparse retrieval. Recent work includes million-scale semantic IDs for advertising recall and video-language representations for temporal moment retrieval.
