    Expert Biostatistician | Ecology · Biodiversity · Conservation · Public Health | R +10 years
    Independent biostatistician with over 10 years of experience, I leverage the power of statistics to understand living systems—whether analyzing wild population dynamics, assessing human impact on biodiversity, modeling species distribution, or backing conservation programs with robust data.

    My specialty: biostatistics applied to ecology and conservation
    I work with researchers, nature reserve managers, environmental NGOs, and consulting firms to transform complex field data into reliable and publishable results.
    The core of my work includes:
    - **Biodiversity Analysis**: alpha/beta diversity indices, rarefaction curves, community similarity analyses
    - **Community Ecology**: ordination (NMDS, RDA, CCA), clustering analyses, assemblage modeling
    -Species Distribution Modeling(SDM/ENM) and ecological niche modeling
    - **Environmental Data Analysis**: time series, spatial data, climate variables
    - **Population Demography and Dynamics**: matrix models, Population Viability Analyses (PVA)
    - **Impact Assessment**: before/after ecological monitoring, anthropogenic pressure indicators
    I master R packages dedicated to ecology: `vegan`, `BiodiversityR`, `ade4`, `unmarked`, as well as advanced visualization tools to present your results clearly and impactfully.
