Current Projects

Endocrine-Disrupting Chemical Exposures and Fetal Organ Development

These studies are the first in humans to examine the relationship between gestational exposure to endocrine-disrupting chemicals such as phthalates and fetal organ development and function. Our findings suggest these gestational exposures may contribute to subclinical structural and functional cardiac and liver adaptations.

Persistent Organic Pollutants and Fetal Growth

This project investigates associations between prenatal exposure to persistent organic pollutants (POPs) and fetal growth and development. Using detailed ultrasound measurements of fetal organ volumes, body composition, and limb dimensions, we examine how individual chemicals and complex chemical mixtures relate to patterns of fetal growth throughout pregnancy.

Age Correction and Growth Assessment in Preterm Children

Accurate assessment of growth among children born preterm requires careful consideration of whether to use corrected or chronological age. Using longitudinal measurements of height and weight, we investigate how differences in growth classification vary by gestational age at birth and age during childhood, with the goal of identifying when age correction is most appropriate. This research aims to inform clinical guidelines for assessing growth in preterm children and improve the accuracy of growth monitoring during early childhood.

Residential Radon Exposure and Brain Cancer Risk

This project explores the association between residential radon exposure and the risk of brain and central nervous system cancer in the Women’s Health Initiative (WHI) cohort. By linking radon concentration data to WHI participant locations, this study examines whether chronic residential radon exposure may contribute to an increased risk of these cancers. This research aims to deepen our understanding of radon as a potential environmental risk factor for brain and central nervous system cancers in the United States.

Validation of Residential Radon Exposure Metrics

Despite their widespread use in epidemiologic research, the comparative performance of existing radon metrics for estimating in-home radon concentrations has rarely been evaluated against independently collected radon measurements. This study aims to assess agreement, bias, and error relative to measured concentrations to inform the selection and interpretation of radon concentration estimates in large cohort studies and strengthen the evidence base for studying the health effects of residential radon exposure.

High-Resolution Modeling of Road Traffic Noise Exposure

Using week-long road traffic noise measurements from over 200 locations in Portland, Oregon, we developed a predictive model to estimate noise exposure levels across the entire city at a 10-meter resolution. The model integrates a range of geospatial variables, including traffic volumes, vehicle speeds, and traffic calming features, along with a novel component that accounts for the noise-shielding effects of buildings. This model provides a valuable tool for future epidemiological studies exploring the health impacts of road traffic noise exposure.
