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:

Single-molecule catalysis. Here we study the catalytic, electrocatalytic, and photoelectrocatalytic properties of nanoscale materials and small-molecule catalysts at the single-turnover temporal resolution and nanometer spatial resolution. The goal here is to acquire chemical knowledge for developing better catalysts for chemical processing, fuel generation, and (solar) energy conversion.

Single-molecule bioinorganic/biophysical chemistry. Here we study the dynamics and mechanisms of the protein machineries involved in cellular metal regulation, trafficking, and efflux both in vitro and in living cells, as well as of molecular processes related to protein folding in living cells. The goal here is to acquire chemical and biological knowledge for developing strategies to cure and prevent diseases.

Method development. In pursuit of our scientific interests, sometimes we develop new methods or extend/improve existing methods to enable new experiments, especially single-molecule/particle level measurements.
