Research
Our research focuses on developing and applying single-molecule techniques to understand molecular processes of physical, bioinorganic, and biophysical in nature. Compared with traditional ensemble measurements, single-molecule approaches remove ensemble averaging, so that transient intermediates and heterogeneous subpopulations can be captured and characterized in both spatial and temporal dimensions and under realistic conditions. Current projects are divided into three main areas:
