Data scientist combining machine learning, Bayesian inference, and cloud-oriented data engineering to deliver reliable analytical pipelines at scale.
Data Science Experience
Data Analyst
Habitat, Montreal, Canada
N/A
2025 - 2024
(1 yr 9 m)
Built and maintained automated, reproducible pipelines for cloud-based spatial data using R, Python, and Julia | Delivered geospatial ML models for client projects | Designed a lakehouse data architecture for efficiently streaming unstructured datasets from Azure storage | Developed a metadata-driven workflow to improve pipeline scalability and governance | Led the team’s transition to Unix, creating automated setup scripts while modernizing the workflows with Docker, CI/CD, and DevOps practices
PhD Research
Integrative Ecology Lab, Sherbrooke, Canada
N/A
2024 - 2017
Built end-to-end analytical pipelines during PhD, from assembling continental forest-climate datasets to implementing mixed-effects, ML, and non-linear Bayesian hierarchical models | Developed open-source R packages (, ) and reproducible HPC workflows to run thousands of model fits at scale. This work formed the basis of one peer-reviewed publication in Ecological Modelling, two preprints (, ), and a technical methods book documenting the full modelling and computational pipeline
Biostatistician
Environment and Climate Change Canada - Quebec, Canada
N/A
2022 - 2020
(part-time)
Developed a cost-aware probability sampling protocol to improve the spatial representativeness of boreal bird surveys in Quebec | Led R&D on spatial bias correction, designing a method later adopted by other provinces | Produced a fully open source, reproducible analytical workflow with automated documentation
