Surface Chemistry of Natural Materials

The primary focus of my research is interfacial processes at mineral surfaces in aqueous environments. Specific research fields expand from understanding thermodynamics of mineralization and dissolution to exploring mutual-effects of bio-molecules on surface structural development. One of the commonly used experimental techniques in my research is Atomic Force Microscopy (AFM). This instrument allows us to observe molecular scale surface process in ambient atmospheric environment as well as under solution flow-through conditions. Data collected from AFM experiments help us to understand how growth/dissolution starts and proceeds in fluid, and where on mineral surfaces bio-molecules and even bacteria prefer to interact. We also investigate the bulk solution processes of mineral-water interactions by analyzing temporal solution chemistry changes. Results of these studies find wide implication and applications in both geosciences and environmental sciences.
