My name is Jae-Hyun Park Klepeis. I met my husband, John, at work and we live in the Peninsula area. The 45 minute ride to and from work gives me time to enjoy a nice Bay view, take nap, or read.

My hobby is cooking, studying recipes, tasting gourmet food, and reading. “To Kill a Mocking Bird” is the best I have read so far. I am currently reading “Les Miserable” which my husband gave me as a present. Going to the gym and playing piano are also activities I enjoy.

I received my B.A. and M.S. at the department of chemistry, Seoul National University, South Korea and my Ph.D degree at State University at New York at Stony Brook under supervision of John B. Parise. My thesis topic was high pressure high temperature synthesis of novel oxides and high dielectric perovskites. I worked as a postdoctoral researcher in Patrick M. Woodward’s group at department of chemistry, Ohio state university for two years. There I focused on structure salvation of new perovskite types and characterization regarding photocatalyst capabilities. I have been working with Choong-Shik Yoo at Lawrence Livermore National Laboratory since 2001

My research interest is crystallography regarding the structure-property relationship. Since pressure is a well-known parameter to change the bond distance and band structure simultaneously I am focused on phase transitions of various systems, d- and f-metals (non-classified subjects) and their compounds, and molecular systems (components of planetary ices). Understanding the mechanism among the series of structures in transitions is my primary goal. So far I have studied synchrotron X-ray and neutron powder diffraction. In the future I plan to pursue single crystal diffraction studies.

I also use Raman spectroscopy as a complimentary tool in the laboratory. To perform high temperature research, laser heating and resistive heating are also adopted in collaboration with my research group members.
