Hi! I am Xinjing Liu (柳心敬). I am currently a first-year Ph.D. student in Artificial Intelligence at the School of Intelligent Science and Technology, Nanjing University (NJU), advised by Prof. Yang Gao and Assoc. Prof. Boyan Wang.

Previously, I received my Master of Engineering (M.E.) degree from Beijing University of Posts and Telecommunications (BUPT) in 2026.

Research Interests

My research centers on multimodal intelligence and its applications in structural biology:

  • Multimodal Learning & MLLMs: Multimodal information interaction, cross-modal representation learning, fusion, and Multimodal Large Language Models.
  • AI for Science (AI4Science): Machine learning frameworks for structural biology, protein design (AI4Protein), and computational drug discovery.
