Expertise

Microplastics risk assessment

I develop and apply risk assessment methods for microplastics in environmental and human health contexts, including drinking water, aquatic ecosystems, exposure assessment, toxicity interpretation, and regulatory decision support. See related research.

Microplastics in drinking water

My work includes scientific and policy applications related to microplastics monitoring, health-based frameworks, analytical methods, occurrence data, and interpretation of microplastics data for drinking water programs.

Environmental toxicology and ecotoxicology

My background spans environmental toxicology, ecotoxicology, analytical chemistry, exposure science, and the interpretation of toxicological evidence for environmental contaminants.

PFAS and toxicokinetics

I work on PFAS toxicokinetics, pharmacokinetic modeling, in vitro-to-in vivo extrapolation, and methods for translating chemical exposure and bioactivity data into risk-relevant metrics.

Computational toxicology and New Approach Methodologies

My work includes data science, machine learning, toxicokinetic modeling, New Approach Methodologies, and open computational workflows for environmental health assessment. See related data science and open tools.

Open science and environmental data tools

I build and support open tools and databases that make environmental health information easier to find, interpret, and use, including resources related to Plastiverse, microplastics, PFAS, and risk assessment.
