Environmental Exposures Biomarkers and Health Impacts

The benefits of nutritional factors on birth outcomes have been recognized, however, limited studies have examined the role of nutritional factors in …www.sciencedirect.com/science/article/pii/S0013935122000020

We work with multiple birth cohorts to study the environmental exposures and biomarkers of exposure/disease, which can help us to understand the underlying mechanism between environmental exposures and disease progress.

Ambient Air Toxics Modeling

Modeled NO2 at 50m resolution in lower Manhattan and downtown Philadelphia.

Over the years, I have been developing air pollution models using dispersion models chemical transport models, satellite products, and land use variables. Our recent study aimed at developing a methods to predict air toxics (e.g., benzene, formaldehyde) at a high spatiotemporal resolution.
