Applied Statistician & Data Scientist | Health, Machine Learning, Causal Inference, R & Python

Profile Summary

I am an applied statistician and data scientist with more than 20 years of experience in statistical modeling, data analysis, and quantitative problem solving across health research, engineering, and industry. My core expertise lies in advanced statistical methods (Bayesian models, mixed models, causal inference, time series), machine learning, and reproducible data science workflows using R and Python. I support projects end-to-end: from study design and data preprocessing to model development, interpretation, and publication-ready results. I have led the statistical responsibility in multiple national and international research projects (including SNF-funded studies), contributed to high-impact peer-reviewed publications, and regularly advise researchers, companies, and institutions on complex methodological questions. What clients value most is my ability to translate complex statistical concepts into clear, actionable insights — without oversimplifying and without unnecessary technical overhead. I work efficiently, independently, and with a strong focus on methodological rigor and practical usefulness. Typical tasks I support: • Statistical consulting and study design • Advanced regression and Bayesian modeling • Machine learning and time series analysis • Health and biomedical data analysis • Reproducible research workflows (R / Python) • Critical review of statistical methods in manuscripts and proposals
