Expand the edge of my life

I am Ziqi (Adam) Chen, a senior undergraduate student in the School of Data Science at The Chinese University of Hong Kong, Shenzhen, pursuing a B.E. in Computer Science and Engineering.

I am fortunate to conduct research with Prof. Hongyuan Zha, Prof. Yixiang Fang, and Prof. Benyou Wang at CUHK-Shenzhen. Currently, I am doing research with Prof. Kexin Pei and Prof. Tian Li at UChicago.

My research interests center on adaptive and efficient language models and agents. I am particularly interested in enabling AI systems to adapt their computation, reasoning, and behavior through interaction and experience, with topics including adaptive computation, agent evolution and efficient reasoning. I am also interested in applying these techniques to AI for Science, especially scientific reasoning and software.

I am actively seeking PhD opportunities starting from 2027 Fall.

See my research and publications for more.

DocMaster: A Hierarchical Structure-Aware System for Document Analysis

Large language models struggle to analyze complex documents such as academic papers and financial reports because existing approaches flatten documents into plain text, discarding structural information. DocMaster parses documents into hierarchical document trees that preserve original layouts and constructs a structure-aware semantic index enabling accurate document filtering and in-depth analysis, with an interactive interface for uploading document collections, building semantic indices, filtering via natural-language queries, and question answering over filtered results.
