Hi, I’m Lequn Chen

I am a Research Scientist at the Advanced Remanufacturing and Technology Centre (ARTC), Agency for Science, Technology and Research (A*STAR), Singapore, specializing in AI/ML applications for advanced manufacturing systems. I completed my Ph.D. in Mechanical Engineering at Nanyang Technological University (NTU) in 2024, following my B.Eng. with Honours (Highest Distinction) in Mechanical Engineering from NTU in 2021.

I’m excited to share that I will be joining Accenture Singapore as an AI/ML Computational Scientist in April 2025.

Professional Experience

I transform manufacturing processes through data-driven approaches and AI solutions. My Experience spans:

AI and Machine Learning

• Developing multi-modal machine learning systems using vision, audio, and thermal data
• Implementing Vision-Language Models (VLMs) for engineering applications
• Developing Retrieval Augmented Generation (RAG) systems and multi-agent frameworks
• Building knowledge graphs and GraphRAG architectures
• Fine-tuning large language models with LoRA and QLoRA techniques

Manufacturing Intelligence

• Designing digital twin frameworks for real-time process monitoring
• Implementing automated feature recognition in CAD/CAM systems
• Developing computer vision systems for defect detection
• Implementing adaptive control algorithms for manufacturing optimization
• Acoustic signal processing for quality monitoring
