Ann Appl Stat 2021 Mar 18;15(1):323-342. Epub 2021 Mar 18.

School of Forestry and Environmental Studies, Department of Environmental Health Sciences, Yale University.

We introduce spatial (DLfuse) and spatiotemporal (DLfuseST) distributed lag data fusion methods for predicting point-level ambient air pollution concentrations, using, as input, gridded average pollution estimates from a deterministic numerical air quality model. The methods incorporate predictive information from grid cells surrounding the prediction location of interest and are shown to collapse to existing downscaling approaches when this information adds no benefit. The spatial lagged parameters are allowed to vary spatially/spatiotemporally to accommodate the setting where surrounding geographic information is useful in one area/time but not in another.

Risk of particulate matter on birth outcomes in relation to maternal socio-economic factors: a systematic review.

Environ Res Lett 2019 Dec 22;14(12). Epub 2019 Nov 22.

School of Forestry and Environmental Studies, Yale University.

A growing number of studies provide evidence of an association between exposure to maternal air pollution during pregnancy and adverse birth outcomes including low birth weight and preterm birth. Prevention of these health effects of air pollution is critical to reducing the adverse infant outcomes, which can have impacts throughout the life course.
