About

Chu-Yin Chang is a pioneering researcher whose work bridges the fields of analytical chemistry, robotics, and agricultural engineering. Her key research areas include ambient mass spectrometry, robotic automation for chemical analysis, and precision agriculture. Chang’s most notable contribution is the development of Robotic Surface Analysis Mass Spectrometry (RoSA-MS), a groundbreaking technique that enables direct chemical analysis of three-dimensional, nonplanar objects—a capability previously limited to smooth, flat surfaces. This innovation, detailed in her 2018 paper (26 citations), eliminates the need for manual sampling and human intervention, opening new possibilities for analyzing complex objects in fields like forensics, art conservation, and materials science. In addition, Chang has made significant strides in agricultural technology with her work on a next-generation image-guided citrus fruit picker (2012, 18 citations), addressing global labor shortages in fruit harvesting. Her interdisciplinary approach—combining robotics, imaging, and chemical analysis—demonstrates a unique ability to solve real-world problems, from automating fruit picking to enabling direct chemical profiling of irregular surfaces. Chang’s work continues to inspire researchers seeking to integrate automation and analytical chemistry for practical, impactful applications.
