Biography

I have more than 20 years of experience in the areas of exposure assessment, risk assessment, risk communication, air emissions modeling, fate and transport modeling, database development, litigation support, and geographic information systems (GIS). I lead interdisciplinary teams to solve complex problems for clients using the best science available. Currently, I perform risk assessments associated with consumer, occupational, and environmental exposure to a variety of chemicals including asbestos, per- and polyfluoroalkyl substances (PFAS), petroleum compounds, dioxins, PCBs, PAHs, and chlorinated solvents. I also use GIS-based site risk assessments to guide remedy and cleanup decisions and have conducted GIS-based region-wide population risk assessments to evaluate the long-range transport of chemicals in the environment. In addition, I have developed and conducted exposure and risk assessments for various air emissions sources such as diesel engines, ceramic product kilns, coal-fired power plants, and coke oven batteries. I have also evaluated exposure and risks from vapor intrusion at residential, commercial, and industrial properties.
