About My Practice

15+ Years of Research, Applied to Your Questions

My consulting practice draws directly on my peer-reviewed research in criminology, behavioral science, and quantitative methods. I have worked with nationally representative datasets, longitudinal studies, organizational surveys, and biosocial samples — and I bring that same methodological rigor to every client engagement.

I work with a selective roster of clients to ensure each project receives careful, high-quality attention. Whether you need help designing a study, making sense of existing data, or building the analytical foundation for a report or grant proposal, I can help.

Prospective clients are welcome to reach out with a brief description of their project. I will respond within a few business days to discuss whether the work is a good fit.
