Grants and research support:

F31 ES029799. Ruth L. Kirschstein National Research Service Award (NRSA) Individual Predoctoral Fellowship. “Arsenic Exposure in US Drinking Water: Spatial Patterns, Temporal Trends, and Related Mortalities.” Award period 2018 - 2021. The proposed study will use several nationally representative databases to explore temporal trends and spatial patterns in drinking water arsenic exposure in the US population and the association between arsenic exposure and related disease at the county-level. There is a critical need to identify susceptible subgroups whose water arsenic remains high, by geography, race/ethnicity, or socioeconomic status, to inform further exposure-reduction interventions. Our study will evaluate the potential impact of federal drinking water regulations on drinking water arsenic exposure and the cardiovascular disease epidemic, determining whether reductions in water arsenic exposure are associated with a reduction in total and cardiovascular mortality.

K.C. Donnelly Externship Supplement, Superfund Research Program. “Mercury exposure assessment in Greater Plains tribal communities.” Awarded 2018. The proposed study will 1) Characterize ambient air and soil mercury concentrations, (2) Determine the association between meteorological conditions and measured ambient air mercury levels, and (3) Engage community members by providing student research opportunities in environmental monitoring research and data dissemination.

Columbia University Center for Environmental Health in Northern Manhattan (CEHNM) pilot grant. “Assessment of mercury and other metals in biospecimens from the Strong Heart Family Study.” Awarded 2018. The proposed study will 1) Characterize variability in metal biomarker concentrations over time and across study centers, and 2) Determine sex-specific differences in metal biomarker levels.
