Wenjie Du

Welcome to my homepage!🤗 I'm Wenjie Du (杜文杰), a MSc student at Nanyang Technological University (2026.01 - now). Previously, I obtained BEng in Computer Science and Technology from Sichuan University in 2024.

I have been working as a research intern in ENCODE Lab of Prof. Huan Wang at Westlake University since Fall 2025. I was also fortunate to work as a research assistant at the Hong Kong University of Science and Technology in 2025, a research intern at the Institute for AI Industry Research (AIR), Tsinghua University in 2024, and a software developer intern at ByteDance in 2023.

I work closely with Yuhao at NTU and Keda at Westlake. I am grateful to all my supervisors, mentors, and friends for their kindness and support throughout my journey!

I am seeking a visiting student position in Summer 2026 and PhD positions starting in Fall 2027.

Research

My research interests lie in large language models and machine learning systems. I focus on understanding the inner mechanisms of these models to improve their efficiency and effectiveness. I am also working towards efficient training and inference systems.

An audio-guided active perception agent that dynamically orchestrates specialized tools to achieve more fine-grained audio-visual reasoning, surpassing leading open-source and proprietary models by substantial margins of 10% - 20% accuracy.

An RL-based method identifies reasoning-critical KV heads in LLMs to enable KV cache compression, achieving 20-50% KV cache reduction with minimal performance loss.

A document-centered framework that converts mobile UI automation into code generation, enabling the script-based mobile GUI agent to achieve higher success rates and lower latency than step-wise agents.

An efficient mobile app exploration agent that uses LLMs for knowledge maintenance rather than action generation, achieving the highest coverage with 148x lower cost than baselines.
