We love to pursue any research problem that excites us and, being optical spectroscopists, we try to solve the problem by shedding light on them. In particular, we plan to develop novel time-resolved optical spectroscopic and microscopic tools to explore a wide range of interesting physical, chemical, biological phenomena in condensed phase (for example, primary processes in photosynthesis).

​

We wish to study (and, hopefully, control!) coherent energy/charge transfer dynamics within natural light harvesters (for example, photosynthetic pigment-protein complexes, fluorescent proteins) as well as within their artificial analogs (for example, molecular aggregates, photovoltaic materials) using femtosecond two-dimensional electronic spectroscopy which are supported by theory of excited-state dynamics

​

We are also interested in understanding nano-scale optical forces using femtosecond laser tweezers for which we have developed analytical theories including nonlinear optical effects and accurately estimated force/potential with numerical simulation.One final dream is to develop a time-resolved super-resolution microscope to spatio-temporally track energy/charge transfer dynamics through complex natural or artificial light-harvesting network.
