    Research Explorations🧐

    My research interests lie in effective and efficient training of large foundation models, especially LLMs, from the following perspectives:
    • Data selection and curriculum design for foundation model training;
    • Efficient pretraining and post-training algorithms;
    • Understanding LLM training dynamics and generalization behaviours;
    • Foundation models for scientific research (AI4Science).
