Research Summary

Ana Navas-Acien is a physician-epidemiologist with a specialty in Preventive Medicine and Public Health and with a long-term interest in the health consequences of widespread environmental exposures. Based on an epidemiologic approach, her research investigates chronic health effects of arsenic, selenium, lead, cadmium and other trace metals. 

Given the paucity of epidemiologic data at low/moderate levels, the possible biological basis, and the controversy for current environmental standards, this challenging area of research is potentially relevant for public health. For exposures with large epidemiologic evidence of the adverse health effects, such as secondhand smoke, her interest is to conduct research in support of progressive policies to reduce involuntary exposure to environmental toxins.
