Hi there, I’m JuiChien!

I am a PhD student in Computer Science at Rensselaer Polytechnic Institute (RPI), advised by Prof. Oshani Seneviratne. My research interests include data evaluation, knowledge graphs (KGs), large language models (LLMs), and the integration of KGs with LLMs to build more explainable and transparent AI systems with stronger reasoning capabilities.

Prior to RPI, my academic journey at Tsinghua University centered on complex industrial system health management and time series synthetic data generation. On the industry side, I completed an internship at Didi Chuxing, where I bridged research and product development to deliver customer-centric solutions. I also serve as a full-time researcher at Deeli AI, where I lead the development of knowledge graph systems, combining them with AI agents to enhance the explainability and transparency of AI, and leveraging KGs as structured knowledge sources for LLMs.
