Building with vision.
Exploring what AI can do.

I work at Delta Electronics’ Delta Research Center (台達研究院) in Hsinchu, Taiwan, where I have been working as an R&D Engineer since September 2026. My focus areas are computer vision, generative AI, and vision-language models (VLMs).

My background is in Data Science and Geomatics at National Cheng Kung University. My work spans image restoration, remote sensing, and vision-language learning, with a focus on developing and evaluating deep learning methods. I’m interested in opportunities to bring these skills to applied AI and engineering teams.
