Portrait of Jun-Peng Jiang

Short Biography

I received my B.Sc. degree from Soochow University in June 2021. In the same year, I was admitted to pursue a Ph.D. degree at Nanjing University without an entrance examination. I am a member of the LAMDA Group, led by Professor Zhi-Hua Zhou, and am supervised by Professor De-Chuan Zhan and Professor Han-Jia Ye.

Research Interests

My research focuses on building intelligent systems that can transform complex, multimodal information into structured knowledge and actionable insights. In particular, I study how machines can jointly perceive, parse, understand, and reason over tables, documents, text, images, and visual structures, with the broader goal of developing data world models and agents capable of interacting with real-world information.

01

Multimodal Tabular Intelligence

Learning from tables together with text, images, and visual structure to enrich tabular signals.

02

Data World Model

Building data world models/agents that parse, understand, reason over, and act on complex information.

03

Document Intelligence

End-to-end document parsing, OCR, document understanding, and structured information extraction.
