Ask better questions. Build defensible answers.
With an M.S. in Measurement & Statistics, a Graduate Certificate in Program Evaluation, and extensive experience designing, analyzing, publishing, and evaluating research, I work with researchers and organizations to make sure the methods fit the question—not the other way around.
The right analysis starts before the analysis.
My approach is collaborative and question-driven. I learn your research context, help sharpen the question, and then identify the design, data, analysis, and communication strategy that best fits what you are trying to learn.
Together, we can work through:
- Research questions and hypotheses
- Study design
- Measurement strategy
- Data preparation and screening
- Statistical analysis
- Model selection
- Assumption checking
- Interpretation
- Data visualization
- Program evaluation
- Manuscript and publication support
- Reviewer response strategy
Broad statistical training, selected to fit the problem.
I work across Python, R, SPSS, SQL, and Tableau and have experience with advanced statistical and research techniques including multilevel modeling, structural equation modeling, meta-analysis, psychometrics, experimental and quasi-experimental design, and mixed quantitative/qualitative research.
Support for people who need rigorous answers and clear interpretation.
Researchers & Faculty
Study design, analysis strategy, advanced statistical support, interpretation, publication, and reviewer responses.
Graduate Students
Theses and dissertations, research design, analysis planning, statistical interpretation, and skill development while preserving the student's ownership of the work.
Organizations & Nonprofits
Program evaluation, outcome measurement, data interpretation, dashboards, and evidence that can support better decisions.
I approach statistics as part of the scientific process, not a separate technical task.
💡 Question First
I start with what you actually need to know. The most sophisticated model is not automatically the best model; the right technique is the one that defensibly answers the question.
📊 Advanced Quantitative Training
My graduate training in Measurement & Statistics and years of applied research allow me to work across design, measurement, modeling, and interpretation rather than focusing on a single software package.
🔬 Active Researcher
I publish, review, design studies, respond to reviewers, collaborate across disciplines, and work with real-world datasets. I understand the full research process and the tradeoffs that happen along the way.
🤝 Collaborative & Educational
I do not want statistical consulting to feel like a black box. When appropriate, I explain the reasoning behind the analysis so you understand what was done, why it was done, and what the results mean.
Flexible support from one question to a full project.
- Statistical Consultation: research questions, design, measures, analysis strategy, or interpretation
- Analysis Projects: data preparation, modeling, visualization, interpretation, and documentation
- Research Design Support: study design, measurement, analytic planning, and evaluation strategy
- Publication Support: methods/results review, statistical response to reviewers, and interpretation
Starting at $200/hour. Project-based pricing is available when scope is clear.
Bring the question—even if the method is still unclear.
We can start by discussing what you are trying to learn, what data you have or plan to collect, where you are in the research process, and what a useful outcome would look like.
