   RESEARCH INTERESTS

My research interests span from fundamental studies of complex mineral-water interface chemistry, biogeochemical interactions and transformation of contaminants (e.g., mercury, perchlorate, uranium and technetium), nanomaterials synthesis, nano-scale phenomenon and spectroscopy, to applied research such as sensor development, studies of natural humic substances in contaminant transformation and field remedial investigations such as permeable reactive barriers and treatment of contaminated water and sediments.
