Development and Evaluation of Methods to Assess Physical Exposures in the Workplace
… Accurately quantifying the level of physical exposures (i.e., kinematics and kinetics) is essential for risk assessments, developing and/or testing interventions, and improving estimates of exposure-response relationships. Such exposures ideally should be quantified in situ, while workers …

Novel Approaches to Exposure Assessment and Dose Response to Contaminants in Drinking Water and Food
… risk assessment and applying novel methods for exposure assessments and dose responses to contaminants in drinking water and foods. Factors that greatly impact contaminant exposures and human dose response include: population susceptibility (i.e., healthy adults or children), different routes of …

Adjusting retrospective noise exposure assessment for use of hearing protection devices
Earlier retrospective noise exposure assessments for use in epidemiological research were not adequately characterized because they did not properly account for use of hearing protection devices (HPD) which would result in potential misclassification. Exposure misclassification has been shown to …

Exposure to hazardous air pollutants in homes
Prior studies have found that human exposure to hazardous air pollutants (HAPs) occurs in homes; however, the depth of these assessments was limited by the extent of the analyzed data. The present Ph.D. dissertation focused on air contaminants of concern in residential buildings, the possible …

Application of a Mobile Flux Lab for the Atmospheric Measurement of Emissions (FLAME)
… much greater spatial resolution for population exposure assessments. The lab's mobility allows it to target specific sources, and plumes from these can be analyzed to determine emission factors. Through eddy covariance, the lab provides the new ability to directly measure emissions of a suite of …
