About

I am a first-year master’s student in Computer Science at Fudan University and a member of DASLab. I received my bachelor’s degree in Software Engineering from Wuhan University of Technology.

Research

My current interests center on the execution layer of data-processing systems: physical operators, data organization, and scheduling. I am exploring how these components can adapt to the demands of heterogeneous AI workloads.

Selected Projects

MindDock

Personal Knowledge System

I am developing a personal knowledge system that connects retrieved information to its sources. My work focuses on source tracking, incremental ingestion, and retrieval evaluation in the RAG backend.

NexDR-Enhanced

Deep Research Agent Extension

An experimental extension of NexDR for academic research. My modifications explore editable Markdown reports, PDF ingestion with page references, and integration with Semantic Scholar and arXiv.

Research Tool

A reusable workflow I designed to help researchers develop and critically evaluate ideas. It guides users through checking evidence, formulating testable hypotheses, and planning small experiments to decide whether to continue, revise, or abandon an idea.
