Research interests

Measurement & psychometrics. How well we measure things drives everything downstream. I work on scale scoring and missing-data decisions (person-mean imputation, prorated scale scores, completeness thresholds), measurement invariance, and structural equation and item response models.

Privacy-preserving synthetic data. With NSWERS, I generate synthetic versions of large, longitudinal administrative datasets and evaluate how faithfully they reproduce the original data (tidysynthesis, syntheval). The goal is analysis that does not expose individuals: as much a question of what can safely be released as of how well the synthesis works.

Applied evaluation & public policy research. At the NEAR Center and the Public Policy Center, I support program evaluation and policy research for state agencies and community partners, from study design and survey methods through analysis and reporting.

Research data infrastructure. Documentation, variable lineage, and reproducible pipelines: the tooling that lets teams trust and reuse their data. This is where my software comes from.

Youth physical activity & exercise physiology. Earlier work covered neuromuscular fatigue, high-intensity interval training, and physical performance testing. See publications.
