ABOUT THE LAB
Exploring Electrochemistry Beyond Conventional Measeurments
The Han Research Group at The Catholic University of Korea develops advanced electrochemical and spectroelectrochemical approaches to investigate chemical and biological processes at interfaces.
Our research integrates electrochemistry with fluorescence lifetime imaging, spectroscopy, and micro/nanoscale electrodes to resolve reaction dynamics with high spatial and temporal resolution.
