Interests

Our group has developed a photoelectrochemical imaging system for functional imaging of cellular processes in real time and with subcellular resolution. Our measurement technology has been shown to be sensitive to the surface charges and the permeability of cell membranes of cells in culture and is also capable of monitoring the concentrations of ions released by cells.
