I am a Materials Research Engineer at the National Institute of Standards and Technology (NIST), where I lead the metrology project for environmental transmission electron microscopy (ETEM). I earned my B.S. and M.S. degrees in Materials Science and Engineering from National Tsing Hua University, Taiwan, and a Ph.D. in Materials Engineering from Purdue University. My research focuses on advancing in situ and operando TEM techniques to study dynamic processes in functional materials at the atomic scale. These measurements provide critical insights into the mechanisms that govern material performance, with applications in carbon dioxide capture and catalytic conversion, as well as semiconductor technologies. I received the Early Career Award from the Nanometer-scale Science and Technology Division of the American Vacuum Society (2019) for pioneering a multimodal TEM approach to reveal key light-matter interactions in plasmonic photochemistry.
