About

I am Hao Liang (梁昊), a Ph.D. candidate at Center for Data Science, Peking University, jointly affiliated with Zhongguancun Academy, and the co-founder of an AI data company. I am a two-time recipient of the President’s Scholarship at Peking University and received the National Scholarship in 2026. I am fortunate to be supervised by Prof. Wentao Zhang and Prof. Bin Dong, and to work closely with Prof. Bin Cui and Prof. Weinan E.

Prior to this, I received my bachelor’s degree from Beijing Institute of Technology, where I was awarded the Xu Teli Scholarship (the highest honor of BIT) and the National Scholarship. I also visited the University of Oxford, working with Prof. Ismail Ilkan Ceylan and Prof. Michael Bronstein.

Research Interests

Data-Centric AI

My research connects data, models, and real-world systems across four directions. For broader context, see our surveys from text-centric and multimodal perspectives.

Data Attribution & Data–Model Interaction

Primary focus

Understanding how individual data shapes model behavior, then closing the training loop through dynamic selection, mixture, and reweighting.

Data Self-Evolution

Building feedback-driven loops in which models and agents continuously generate, evaluate, select, refine, and reuse data as capabilities evolve.

On-policy feedbackTargeted synthesisExecutable verificationSkills & memory

Data Infrastructure

Scalable infrastructure across the full data lifecycle—from preparation and training-time adaptation to inference-time knowledge access.
