Expertise

Analytical & Environmental Chemistry

Research Interests

Analytical Chemistry, Environmental Analysis, Carbon Dioxide Emulsions, Artificial Photosynthesis, Humic Materials, Fluorescence Spectroscopy, Metal Speciation, Vitamin E Oxidation Reduction, Enhanced Oil Recovery

Fluorescence quenching and enhancement phenomena are being utilized to assess binding reactions of metal ions and organic compounds including fulvic and humic acids, Alpha-tocopherol (vitamin E) is being studied to elucidate oxidation and reduction reactions, Liquid and supercritical carbon dioxide droplets are stabilized by particles creating emulsions that have several advantages for carbon dioxide sequestration in geologic formations or the deep oceans and can also be employed for enhanced oil recovery and other valuable applications, Artificial photosynthesis research is being conducted to convert carbon dioxide and water into hydrocarbon fuels
