My research focuses on the geochemical and hydrological processes controlling the transport and fate of toxic contaminants and nutrients in coastal and subsurface environments. I am interested in conducting field investigation, laboratory experimentation, and geochemical-hydrological modeling to elucidate chemical and physical processes of environmental systems from the field to the molecular scale. I have been utilizing various types of advanced instruments such as X-ray Absorption Spectroscopy (XAS), Transmission Electron Microscopy (TEM), X-ray micro-tomography (XMT), and Scanning Electron Microscopy (SEM) to develop a fundamental and mechanistic understanding of environmental processes.
