About Pierre

I am a PhD-level aquatic ecologist with strong expertise in aquatic entomology, floodplain ecosystem dynamics, biodiversity prediction, and contaminant transfer.
I combine ecological knowledge with advanced analytical skills, including mixed-effects modelling, machine learning approaches, and predictive modelling in R.

I have worked with various organizations dedicated to the protection of aquatic ecosystems, and I regularly support research teams, environmental consultancies, and public agencies in the interpretation of biological data (fish and aquatic invertebrates)

I provide rigorous scientific writing, review, and methodological support for research projects, environmental reports, grant proposals and deliverables.

Services Offered:
1️⃣ Scientific Writing & Editing (EN/FR)
- Proofreading and editing of reports, articles, and EU deliverables
- Improving structure, clarity, and style
- Ensuring scientific accuracy and methodological consistency

2️⃣ Ecological Data Analysis (R)
- Mixed-effects models (GLMM, GAMM)
- Predictive modelling and machine learning
- Multivariate analyses, bioassessment, ecological indices
- Data visualization

3️⃣ Aquatic Ecology Expertise
- Interpretation of macroinvertebrate data
- Ecological status assessment
- Fish recruitment analyses
- Contaminant transfer assessment

4️⃣ Taxonomic Identification
- Species-level identification of caddisflies and chironomids
- Taxonomic validation for monitoring and restoration studies

5️⃣ Scientific & Technical Writing
- Technical notes and reports
- Literature reviews
- Methods and results sections of articles

6️⃣ Training & Support
- Introduction to R for entomologist
- Multivariate analysis
- Bioassessment and interpretation of aquatic invertebrate data
- Aquatic entomology (caddisflies and chironomids)

📅 Availability
Flexible — short-term missions in editing, analysis, or ecological expertise.
Approximately 5–10 hours per week.
