Research Interests

Jae-Hyun Park Klepeis received her PhD in chemistry under the supervision of Professor John Parise at State University of New York at Stony Brook in 1999. After finishing two years of postdoctoral research in the structure–property relationship of metal oxide systems in search of photocatalysts at Ohio State University, she joined the High Pressure Physics group at Lawrence Livermore National Laboratory in 2001. Since then, she has been working on molecular systems, metals, and metal compounds in diamond anvil cells under high pressure-high temperature conditions. She uses x-ray diffraction techniques as the primary tool to probe the structures, equation of states, and strength.
