PhD-qualified Statistical Consultant specializing in advanced quantitative modeling and research-focused statistical support for researchers, doctoral scholars, academic authors, clinical teams, and professional research groups. My work includes causal inference for observational and real-world evidence studies, survival and competing-risk analysis, longitudinal and mixed-effects modeling, Bayesian hierarchical modeling and evidence synthesis, HEOR/HTA cost-effectiveness analysis, LPA/LCA and mixture modeling, SEM/CFA, mediation and moderation, regression and applied econometric modeling, psychometric analysis, meta-analysis, and sensitivity and robustness assessment. I support projects from research-question and analysis-plan review through model selection, diagnostics, statistical interpretation, publication-ready tables and figures, statistical Methods and Results development, methodological revision, and reviewer-response support. I work primarily with R, Mplus, Python, Stata, and SPSS, with emphasis on reproducible analysis, transparent assumptions, appropriate interpretation of uncertainty and limitations, and conclusions that remain within the evidence. My preferred working style is clearly scoped, milestone-based statistical consulting with defined deliverables and careful written communication.
