I am a staff research engineer working on large language models (LLMs) at Baidu NLP. Before that, I was associated with Institute of Automation, Chinese Academy of Sciences (CASIA). I graduated from Edinburgh Informatics in 2018 under the supervision of Adam Lopez and Naomi Saphra.

My research endeavors revolve around generative AI, with a particular emphasis on:

  • Pre-training, instruction tuning, in-context learning, and their variants across languages, modalities, and tasks;
  • AI alignment and scalable oversight;
  • Multimodal deep generative models.
