Recent research has focused on mechanistic understanding of bacterial adhesion to mineral surfaces (e.g., silica, alumina and iron hydroxide) and sorption and redox chemistry of biogenic nanoparticles (e.g., manganese oxide and iron sulfide). My research interest also includes development of "mineral-inspired" energy materials (e.g., photoconductive material and high-temperature superconductive material). Current research includes corrosion processes of nuclear-waste glass and CO2 diffusion in ice crystals. Research approaches incorporate spectroscopic experiments and molecular modeling computations.
