Welcome to the Kim Environmental Geochemistry (KEG) Lab at Chapman University! Led by principal investigator Dr. Christopher Kim, the KEG Lab is located in the Schmid College of Science and Technology at Chapman University.

Combining laboratory studies, field sampling, and research at X-ray synchrotron facilities, members of the KEG Lab conduct independent research on current environmental problems involving metal contamination in natural settings. The lab’s main research focuses are: (1) The behavior of nanoparticle aggregation and adsorptive properties in natural systems, and how these behaviors relate to heavy metal transport and remediation in natural systems and (2) Understanding the transport of heavy metal(loid) contaminants in mining systems, such as arsenic, and the acute and long-term effects they pose to both humans and the environment.
