Research Interests
My research interests are broad-based and applied, encompassing environmental exposure assessment, risk assessment and regulatory toxicology.
The role of the regulatory toxicologist is to make decisions, generally with very limited data, that will prevent, or at least minimize, adverse affects to human health and the environment while, at the same time, attempting balance the concerns of the regulated community. My interests are to develop tools, through applied research, for regulators as well as risk assessment professionals, to achieve these goals.
- Development of passive sampling devices that integrate concentrations of contaminants in the aquatic environment over time. This includes the semipermeable membrane device (SPMD) as well as other artificial substrates such as low-density polyethylene strips, or solvent / sorbent-filled membranes.
- Integration of human and ecological risk assessment. Often there is a large duplication of effort when assessing risk for human and ecological receptors. By examining current paradigms we can improve and streamline the processes and better protect human health and the environment.
