We focus at the application of time-resolved spectroscopic methods to investigate the interdisciplinary fields, including ultrafast spectroscopic study of electron and energy transfer in photosynthetic process, interfacial charge recombination process, photoinduced carrier relaxation probed by time-resolved mid-IR spectroscopy, fast protein folding kinetics investigated by temperature-jump ns time-resolved mid-IR spectroscopy, molecular probe for wettability conversion at individual TiO2 nanoparticles. We are also interested in developing novel technique in ultrafast spectroscopic study. Recently we have developed a transient fluorescence spectrometer for acquisition of femto-second time-resolved fluorescence spectra by photon-to-photon amplification with a gain factor of 106 based on the principle of noncollinear optical parametric amplifier. Besides, we are also interested in exploring the physico-mathematical description of plant morphology at cellular level.
