The Motivation Lab and Michigan Roybal Center in the School of Kinesiology are seeking a Biostatistician to serve as the quantitative backbone across the full lifecycle of the lab's behavioral, observational, and clinical intervention research. This position is embedded in an interdisciplinary research team led by Principal Investigator David E. Conroy, Ph.D., and works closely with co-investigators, project managers, and clinical research staff on NIA-, NHLBI-, and NIDDK-funded studies spanning precision behavioral intervention science, mHealth, just-in-time adaptive interventions (JITAIs), and rigorous clinical trial methodology.
This is a 12-month, term-limited position contingent on continued grant funding. Renewal beyond the initial term is possible but not guaranteed.
This role bridges traditional biostatistics and modern data science, handling everything from prospective power analyses and data architecture design through advanced longitudinal modeling, machine learning, and data sharing in open-science repositories. The ideal candidate is recognized as a subject-matter expert in quantitative methods, works independently with a high degree of autonomy, and is comfortable both executing complex analyses directly and reviewing/mentoring the work of less experienced analysts.
(EF) = Essential Function
Study Planning & Methodological Design (20%)
- Perform sample size and power calculations, including simulation-based power analyses in R, for complex study designs prior to data collection.
- Design data management protocols, randomization strategies, and data architecture for clinical trials and observational cohorts.
Complex Statistical & Data Science Analysis (45%)
- Conduct advanced statistical analyses across cross-sectional, prospective longitudinal, randomized controlled trial (RCT), and intensive longitudinal data (ILD/ecological momentary assessment/wearable or passive sensor) formats. (EF)
- Implement frequentist mixed-effects models and generalized estimating equations in R (lme4, nlme, glmmTMB). (EF)
- Model latent variables, structural equations, and longitudinal growth patterns in Mplus or R.
- Diagnose missing data mechanisms and apply modern handling methods (e.g., FIML, multiple imputation) suited to longitudinal attrition. (EF)
- Apply advanced hierarchical/multilevel models using both frequentist (lme4, glmmTMB) and Bayesian (Stan, brms, rstan) approaches as appropriate to the research question. (EF)
- Build and evaluate time-series machine learning and deep learning pipelines in Python (scikit-learn, PyTorch).
Data Governance, Safety Monitoring & Open Science (20%)
- Prepare interim reports, safety metrics, and blinded/unblinded summaries for Data Safety and Monitoring and funding sponsors (e.g., NIH). (EF)
- Establish data management frameworks that ensure data integrity, HIPAA/IRB compliance, and reproducible analytic pipelines.
- Package, annotate, and document clean codebooks, datasets, and analysis scripts for deposit in public/restricted repositories (e.g., ICPSR, GitHub). (EF)
Collaborative Dissemination, Documentation & Mentorship (15%)
- Lead the development and team-wide adoption of best practices for study documentation, reproducible analytic workflows, and data management standards. (EF)
- Co-author peer-reviewed manuscripts, grant applications, and conference presentations, contributing statistical methods text, methodological descriptions, and publication-grade data visualizations.
- Review and provide feedback on analytic code and outputs produced by less experienced lab staff or trainees; serve as a technical resource on quantitative methods within the lab. (EF)
- Master's degree or Ph.D. in Quantitative Psychology, Biostatistics, Data Science, Applied Statistics, Information Science, or a related quantitative field, or an equivalent combination of education (with a minimum of a Bachelor's degree) and experience.
- 3+ years of post-degree experience supporting health, behavioral, or clinical research projects.
- Demonstrated hands-on proficiency in both R and Python for statistical computing and data science workflows.
- Experience with intensive longitudinal or ecological momentary assessment (EMA) data, including passive sensor/wearable data streams.
- Experience with reproducible research workflows, including version control (Git/GitHub) and dynamic reporting tools (Quarto, R Markdown, or Jupyter Notebooks).
- Demonstrated experience producing publication-grade data visualizations (e.g., ggplot2, matplotlib/seaborn, or si
