Air Pollution and Traffic Exposures

In the SpaCE2 Lab, we have a long history of exploring the adverse health effects of exposures to air pollution and traffic exposures.  Below are key papers from our group in this area and details of ongoing projects. We are always looking for exceptional students and postdoctoral fellows interested in research in this area.

NIH/NIEHS R01 ES029840-01A1: Early life exposure to the natural, built, and social environments and incident hypertension

Diet, obesity, and physical activity are known risk factors, and a growing body of evidence suggests that exposures to air pollution are also associated with risk; however, to date, no study has been able to examine the role of multiple environmental exposures throughout childhood on risk of subsequent hypertension in adulthood, nor how environmental exposures interact with features of the built and social environments to influence risk. We aim to explore the impacts of features of the natural, built, and social environments throughout childhood on risk of hypertension in adulthood, to provide valuable information for future risk assessments and population level prevention.

NIH/NIEHS R01 ES0262460: Statistical Methods to Account for Exposure Uncertainty in Environmental Epidemiology

In this proposed research, we will take a life course approach, as consistent with NIEHS strategic priorities, focusing on methodological needs in several critical areas of environmental health, including the effects of constituents of air pollution and of aspects of the neighborhood environment on cardiovascular disease and its precursors and consequences, including all-cause mortality, obesity, type 2 diabetes and subclinical cardiovascular biomarkers.

NIH/NIEHS R01 ES028712-01: The Effects of Environmental Exposures on Semen Quality and the Sperm Epigenome

The aims of this project are to assess the impact of multiple environmental exposures (air pollution and endocrine disruptors) on measures of semen quality (concentration, total count, and motility) assessed via cell phone, morphology assessed with standard laboratory methods, and novel epigenomic markers (sperm DNA methylation).

NIH/NIEHS R01 ES028033: Relationship Between Multiple Environmental Exposures and CVD Incidence and Survival: Vulnerability and Susceptibility

The major goals of the proposed project are to study associations of multiple environmental exposures on cardiovascular disease (CVD), mortality and survival after a non-fatal CVD event in the context of multiple confounders and effect modifications. We will be developing new statistical methods, assessing air pollution (particulate matter, nitrogen dioxide, and ozone) and weather (e.g. temperature variability) as main effects, and evaluating effect modification by contextual, lifestyle and genetic factors

NIH/NIEHS R01 ES0227696: Air pollutants and cardiovascular risk: Investigating thresholds with pooled cohorts and electronic health records

This project investigates the relationship between long-term exposures to air pollution and the development of cardiovascular disease. Using both (1) pooled high-quality cohort studies and (2) health system records based on electronic health records (EHR), this project will evaluate this concentration-response curve focusing on the shape and the presence of a threshold for exposure.
