Freelance Statistician & Data Analyst | R, Matrix Sensitivity Analysis, ggplot2 (10+ years)

Profile Summary

I am a statistician and data analyst with extensive experience using R for ecological, evolutionary, and demographic research. My work focuses in particular on matrix population models, sensitivity and elasticity analysis, and the interpretation of structured population dynamics in long-lived organisms. I have over a decade of experience working in R, including the development, analysis, and visualisation of matrix models for life-history evolution, population growth, and density-dependent processes. I am especially comfortable with matrix sensitivity analysis, life-table response experiments (LTRE-style decompositions), and translating complex model outputs into clear, interpretable results. A major strength of my work is figure creation and scientific visualisation. I am highly proficient in ggplot2 and routinely produce publication-quality figures that are clean, informative, and tailored to academic journals, grant reports, and technical presentations. I also use R Markdown to generate fully reproducible analyses and reports. My current research projects include density-dependent analyses of life-history evolution in long-lived orchids, with an emphasis on senescence, survival–reproduction trade-offs, and demographic buffering. This work integrates matrix modelling, sensitivity analysis, and careful visual communication to support both theoretical insight and applied interpretation. I am comfortable collaborating with researchers across ecology, evolution, conservation biology, and related fields, and I place a strong emphasis on clarity, reproducibility, and methodological transparency in all analytical work.
