I am a Beamline Scientist at HPCAT (High-pressure Collaborative Access Team) Sector 16 of Advanced Photon Source. The HPCAT is administrated by Geophysical Laboratory, Carnegie Institution of Washington. I am responsible for developing novel high-pressure synchrotron x-ray techniques, supporting HPCAT operations and conducting original research. My research interests include amorphous and liquid structure of refractory materials under high pressure, structure and property correlations, and physics and chemistry of mineral-fluid interfaces.
        Briefly introducing my background, I was educated in minerals and petroleum engineering (a.k.a. mining engineering) at Seoul National University, S.Korea and got a master degree in applied geochemistry there. For my master thesis, I studied influence of hydraulic system characteristics to regional aqueous geochemistry. My life-long commitment  on mineral-water interface studies originated from this early research experience. Having been trained in applied geochemistry, I got a Ph.D. degree in materials sciences from Tohoku University, Japan. The change in major also change my life fundamentally to become a scientist. For my Ph.D. thesis, I studied local atomic ordering  in amorphous and liquid materials using anomalous x-ray scattering method.
        My expertise is modern synchrotron x-ray techniques for materials characterization and structure analysis. I made a major contribution to development of resonant anomalous x-ray reflectivity (RAXR) technique for mineral-water interface studies during post-doctoral training. Inheriting from multidisciplinary experiences, my research interests have expanded on over time from amorphous and liquid structure to physics and chemistry of mineral-fluid interfaces and structure and property correlations.
        Currently, I am developing user science programs at HPCAT including combined micro-XRD and x-ray absorption spectroscopy for high-pressure research, Paris-Edinburgh cell applications for thermoelectric property measurements. I am also conducing a research of high-pressure surface and interface processes.
