Projects
Research programs, data tools, and scientific-community work
The work below spans the research programs I lead at the U.S. EPA, the data tools and collaborative trials I’ve contributed to, and the funded studies I’ve taken part in. Each entry is drawn directly from my record.
Research leadership
Programs led under the EPA’s Chemical Safety for Sustainability (CSS) Strategic Research Action Plans (STRAP).
Output Lead · STRAP 4
Building confidence in non-targeted analysis for exposure assessment
Leads CSS 402.6 — building confidence in the use of non-targeted analysis for exposure assessment through applications.
Product Lead · STRAP 4
Point-of-use water filters + NTA for CECs in drinking water
Using point-of-use water filters and non-targeted analysis to identify contaminants of emerging concern in drinking water.
Product Lead · STRAP 4
Increasing confidence in NTA using gas chromatography
Improving the reliability of non-targeted analysis identifications through GC-based methods.
Product Lead · STRAP 4
Characterizing household-material emissions during a fire
Applying non-targeted analysis to characterize emissions from household materials during a fire.
Product Lead · STRAP 3
NTA for rapid-response chemical characterization
Case-study application of non-targeted analysis for chemical characterization in a rapid-response scenario.
Data tools & collaborative science
Collaborative trial
EPA Non-Targeted Analysis Collaborative Trial (ENTACT)
Co-chaired the ENTACT International Workshop (Durham, NC, 2018) and chaired national-meeting sessions on its results. Contributed the in-house mixture and house-dust performance findings (STAA Honorable Mention, 2021).
Cheminformatics tool
CompTox Chemicals Dashboard Team
Member of the team behind EPA’s CompTox Chemicals Dashboard, supporting structure identification for non-targeted analysis.
Community · Standards
Benchmarking & Publications for Non-Targeted Analysis (BP4NTA)
GC-NTA Committee Chair (2024–present) and former Website Committee Chair (2020–2023) for the NTA community working group.
Editorial
Guest Editor — special issue on NTA of the environment
Guest Editor for the special issue “Non-Targeted Analysis of the Environment” in Environmental Science & Technology and ES&T Letters.
Funded research (participant)
Externally funded studies I contributed to:
- Tapwater Analysis Project (TAP): Testing Chemicals in Drinking Water in California — California Breast Cancer Research Program, California Breast Cancer Prevention Initiatives, 2019.
- Fire and Water: Investigating Drinking Water Contamination in Paradise, California after the Camp Fire — National Institute for Environmental Health Sciences, R21 program, 2019.
- Application of community-engaged and discovery-driven methods to characterize drinking-water contaminants in disadvantaged communities and their perinatal health effects — NIEHS Superfund Hazardous Substance Research and Training Program (application), 2021.
Peer-reviewed outputs from many of these efforts are listed on the Publications page.
