Mahmoud O.
Researcher | Biostatistician | from Data to Publishable Results
Most medical studies fail due to weak structure and poor statistical analysis — not weak ideas. I help researchers turn raw data into clear, defensible, publishable results suitable for peer-reviewed journals. I’m an ECFMG-certified physician and biostatistician with 8+ years in clinical research, medical data analysis, and biostatistics for research, with 25+ peer-reviewed publications (H-index: 7). I understand what reviewers expect — and how to ensure your clinical data analysis stands up to scrutiny. What I deliver: • Statistical Analysis (R, Python, SPSS, Jamovi, JASP): hypothesis testing, correlation analysis, regression (linear, logistic, Cox), survival analysis (Kaplan–Meier, log-rank), multilevel models, and propensity score matching • Clinical Data Interpretation & Visualization: clear, clinically meaningful insights from medical datasets, with professional tables, graphs, and figures • Publication-Ready Results: structured results sections, statistical reporting, and formatting aligned with journal publication standards Why clients work with me: • MD + biostatistician → strong understanding of clinical research methodology and data analysis • Proven track record in medical research and peer-reviewed publications • Focus on accuracy, clarity, reproducibility, and publishability Scope: • Advanced data analysis, clinical research, medical datasets, observational studies, randomized trials, epidemiological studies, meta-analysis Not a fit for: • Student assignments or homework • Ghostwriting full papers from scratch • Low-quality or unethical research work If you need biostatistics for medical research, clinical data analysis, or statistical support for publication, let’s discuss your project.
