Designed and oversaw project that developed rankings for the effects of seven different chemical, biological, and physical stressors on stream structure and function, using 100+ laboratory mesocosms.

Investigated the mechanisms underlying the toxic effects of titanium dioxide nanoparticles (n TiO2) to freshwater phytoplankton. Examined algal physiology, competition with bacteria, and interactions with UV light and the effects of n-TiO2 on algal chlorophyll content.

Studied fate and effects of titanium dioxide nanoparticles in artificial stream mesocosms, and the relationships between concentrations of n-TiO2 in algal biofilms, algal biomass, and species diversity.

In collaboration with other scientists, reviewed the effects of room-temperature ionic liquids on aquatic organisms and published an invited paper on the topic.

Used standard acute toxicity tests to determine the toxicity of several room-temperature ionic liquids to freshwater algae, and examined the role of cell wall structure in determining toxicity.

Provided technical support to natural resource damage assessment (NRDA) of the Deepwater Horizon oil spill.

Provided analysis of fisheries catch data to identify causal linkages between upstream water usage changes and downstream effects for a litigation matter before SCOTUS.

Supported a net environmental benefits analysis (NEBA) for the closure of coal-fired power plants by evaluating human health risk assessments for coal ash basins at six sites.

For a pharmaceutical company, reviewed the life history of dung fauna invertebrate communities in support of registration of cattle antiparasitic treatments.

Provided statistical support in generating point estimates of lethal and sublethal effects for laboratory toxicity tests.

Performed research on historical baseline conditions at several coastal areas to which to compare current alleged injuries in support of litigation.

Managed reporting for a pilot study testing the efficacy of activated carbon sediment amendments in field and laboratory trials at reducing bioavailability of mercury and PCBs. Reviewed historic site operation materials for potentially responsible parties (PRPs) to assist in development of an allocation model for costs associated with remediation of contaminated river sediments.

Reviewed historic site operations, waste handling, and environmental data for clients in light of retrospective state-of-industry-knowledge to recover insurance-covered remediation costs.

Performed a literature review on the ability of microplastics in the environment to serve as vectors for hydrophobic organic contaminants. Review was submitted and accepted for publication.

Performed a screening level ecological risk assessment (SLERA) for an industrial facility discharging formaldehyde in anticipation of government changes to wastewater effluent restrictions.

Evaluated trends in water quality over time at multiple cities across the USA to support a causal analysis of air emissions on the environment.

Performed a site assessment of an aquaculture facility in support of an environmental assessment for AquAdvantage® salmon for AquaBounty Technologies, Inc.

Performed a literature review on the effects of refined coal-tar pavement sealants on aquatic environments.

Collected sediment cores in a tidal wetland as part of a study to determine long-term efficacy of activated carbon sediment amendments.

Estimated ecological risk to wildlife that use wetlands near a former hospital that had soils with elevated metals.

Evaluated an expert report on aquatic bioassay results in support of litigation. Contributed to preparation of a rebuttal report, in which we showed that the opposing expert's report was critically flawed in numerous ways.

Contributing author on revision of Organisation for Economic Co-operation and Development (OECD) Guidance Document on Aqueous-Phase Aquatic Toxicity Testing of Difficult Test Chemicals.

Prepared white paper on macroplastics in the environment, which covered sources, characterization, fate and transport, human and ecological effects, and identified key knowledge gaps.

Project manager and senior ecotoxicologist for a large, multi-facility evaluation of effluent toxicity including chemistry, process wastewater evaluation and toxicology assessment.
