Select Projects

Safety Assessment for Medical Implant:  Performed a toxicological evaluation of oil residuals on medical implants.  Assessed the potential for long-term effects.

Pesticide Spray Drift Evaluation:  Developed a sampling plan to assess air concentrations of pesticides, and performed a risk assessment for spray drift exposure to pesticides.

Historical and Current Knowledge of Asbestos:  Evaluated evolution in understanding of asbestos health effects in different industries over time.  Analyzed toxicological differences among forms of asbestos.

Evaluation of Toxicology and Risks of PFOA and PFOS:  Provided comments to US EPA regarding its Health Effects Documents for PFOA and PFOS.

Toxicological and Risk Evaluation of Arsenic:  Evaluated arsenic mode-of-action and assessed the implications for low-dose risks.

Toxicological and Risk Evaluation of Perchlorate:  Conducted an in-depth evaluation of animal toxicological studies in terms of human relevance.  Coordinated a human volunteer study involving low-level perchlorate exposure.

Testimony at Congressional Briefing on Lead Exposure from Recreational Vehicles:  Presented an analysis of the Consumer Product Safety Improvement Act on exposures to lead and potential impacts on blood lead of lead released from valves on bicycles and motorcycles.
