Ja-Hon Lin received the Ph.D. degree from the Institute of Electro-Optical Engineering, National Chiao Tung University, Taiwan, in 2002. From 2003 to 2007, he worked as a Postdoctoral Fellow at the same institute. In 2007, he joined the Department of Electro-Optical Engineering at National Taipei University of Technology as an Assistant Professor and has been a Professor since 2015. He served as Chief of the Research and Project Section, Research Development Office, from 2014 to 2020, and as Vice Dean from 2020 to 2021. In 2022, he was appointed Distinguished Professor at National Taipei University of Technology. He was listed among the World’s Top 2% Scientists in the Stanford University global ranking in 2024 and 2025.

His research focuses on the photophysical properties of advanced electro-optical materials and nanophotonic systems, including perovskite semiconductors, organic functional materials, and nanostructured photonic architectures. He investigates carrier dynamics and nonlinear optical phenomena in optoelectronic semiconductor materials, as well as microstructured laser systems such as random and distributed feedback (DFB) lasers. His work further extends to materials-enabled sensing technologies using Raman spectroscopy and electrochemical methods for pesticide and pharmaceutical detection.
