Hello, I am Yuchen Xia.

I am a postdoctoral researcher in industrial AI, working on LLM agents, digital twins, and autonomous industrial systems. Since 2021, I have focused on this research direction, led two R&D projects on industrial agent systems, and developed multiple LLM-powered solutions deployed in real-world industrial applications.

Research Highlights

LLM Agents + Digital Twins for Pharmaceutical Manufacturing — Technology Transfer Project — University of Stuttgart × AstraZeneca PLC
Technical lead for a technology transfer project developing an AI multi-agent system to support and accelerate pharmaceutical process development. LLM agents autonomously conduct controlled experiments using high-fidelity simulation models embedded in digital twins, and turn the resulting evidence into actionable process recommendations.

Following the successful Phase I proof of concept, Phase II focuses on scaling the system to solve more complex tasks through model orchestration and automate multi-objective optimization.
