Dr. Kim specializes in evolution of pelitic rocks over the range of burial diagenesis to low-grade metamorphism, clay mineralogy, microbes-clay mineral interaction, and microstructure of shale. Recently Dr. Kim studied the effects and a mechanism of microbial reduction in clay structures. He focused on the structural changes of bioreduced Fe-rich smectite. He discovered the neoformation of illite phase in bio-reduced smectite sample at room temperature, indicating that microbes play a significant role in promoting the smectite-to-illite (S-I) transformation. These results that challenge the conventional concept of S-I transformation and of reaction kinetics have far-reaching implications in maturation of petroleum, changes in pore water chemistry, geopressuring of shale and formation of growth fault. The paper for these findings was published in “Science” (Feb, 2004). He also found that the flocculation properties of fine smectite particles including settling velocity and floc size were modified by the microbial Fe(III) reduction in clay structure. These results can be applied to the contaminant remediation technique in aquifer. Dr. Kim has performed a vast amount of research on the physical properties of fine-grained sediments with a specialty on the consolidation and permeability characteristics of marine clays, muds and shales. He has also performed extensive research on the microfabrics of fine grained sediments. Dr. Kim also has worked integrated study of the migration and entrapment of hydrocarbons. He focused on the sealing properties of shale such as capillary pressure and permeability. A list of selected Dr. Kim’s activities follows.
