My research spans the areas of electronic and structural dynamics of elementary reactions in condensed phase. I have special interest in nonequilibrium photoinduced phase transformations of materials, ultrafast electron-phonon interactions in correlated materials, photoinduced dynamics in nanometer-sized materials, ultrafast chemical dynamics, and ultrafast hydration dynamics in biological systems. Femtosecond-resolved electron microscopy (imaging, diffraction, and spectroscopy) and femtosecond-resolved optical spectroscopy, each of which stands alone as a powerful tool in ultrafast dynamics studies, are utilized together pursuing the scrutiny of the exciting subjects above.

Senior Scientist/Postdoctoral Scholar at Caltech
2005.10 - 2013. 5
Under the supervision of Dr. Zewail, a Nobel laureate in chemistry, I have built a femtochemistry laboratory (036) in "Femtoland" at Caltech in 2006. Combining a femtosecond-resolved fluorescence upconversion spectrometer and a picosecond-resolved time-correlated single-photon counting spectrometer, I have studied elementary chemical reaction dynamics, ultrafast photo-mutagenesis of a model DNA base pair, and ultrafast hydration dynamics of proteins. Since 2006, I have joined a team to develop the 2nd-generation UEM (UEM-2) and reported its powerful applications in various fields of science.
Advisor: Prof. Ahmed H. Zewail
Postdoctoral Scholar at Seoul National University
2004. 9 - 2005. 9
Taking advantage of the picosecond time resolution of a streak camera, I have investigated activation-controlled chemical reaction dynamics in solutions. The knowledge attained in neat systems have served for unveiling reaction mechanisms in a series of heterogeneous nano-media, such as micelles, cyclodextrins, and zeolites. The fundamental studies have been extended for understanding mechanisms of light-emitting devices and lead to develop organic light-emitting/laser materials.
