About:
Research interests involve metabolic interactions of essential microelements, especially trace metals, with toxic metals and metalloids that contaminate food chain and drinking water reservoirs. Research topics include: the interactions between selenium, an essential micronutrient, and arsenic, an environmental contaminant and human carcinogen; the enzymes and co-factors involved in the metabolism of arsenic and selenium; the mechanisms of arsenic- induced diabetes; and, the role of nutritional antioxidants and antioxidant enzymes in responses to the oxidative stress induced by exposure to environmental toxins, by viral infections or nutritional deficiencies.
