Dr. Nicole Deziel's research is designed to enhance understanding of the interface between exposure to environmental agents and human disease, including women's health and children's health outcomes. She is focused on evaluating, improving, and developing exposure estimates for application in environmental epidemiologic studies. She investigates critical methodologic issues, such as (1) what is the relative contribution of different routes of exposure to an environmental agent, (2) what are the between- and within-participant variability in exposure measurements over time, and (3) how well do surrogate exposure measures, such as questionnaire responses or GIS-based approaches, compare to biological or environmental measurements? She has investigated these questions within the context of several types of pollutants including pesticides, persistent organic pollutants, and polycyclic aromatic hydrocarbons. Dr. Deziel is also investigating how environmental exposures are changing with new techniques for energy production (e.g., hydraulic fracturing) and climate change.
