Research Interests

I am interested in time resolved spectroscopy studies that explore excited state, energy and electron transfer dynamics in a solar energy conversion system. My main techniques are time-resolved spectroscopy (Including transient absorption and fluorescence spectroscopy, time from femtoscond to millisecond, wavelength range from UV-vis to Mid-Infrared), and relative photophysical technologies.
