As global demands on fresh water resources escalate, there are mounting pressures on natural systems and increasing needs to find sustainable solutions to address global water and sanitation challenges. My research investigates degradation of organic contaminants in water reuse systems and uses optical spectroscopic techniques for rapid tracking of contaminants in these engineered systems. In natural systems, my research has delved into the biogeochemical processes that influence mobility of toxic trace elements, such as arsenic, and the transformation and natural degradation processes for aquatic organic contaminants. An important part of that is advancing our understanding of how natural organic matter (NOM) interacts with solutes, sediments, and microorganisms to influence water quality in pristine and polluted environments.
