Data Science & Geospatial Consultant
I help organizations apply statistics and machine learning to climate, health, and geospatial data, turning it into models and tools that support real-life evidence-based decisions.
Get in touchSpatial models and risk indices from satellite, climate, hazard and vulnerability data
Combining epidemiological and environmental data to track outbreaks and inform policy.
Bayesian inference and reproducible pipelines (R, Python, Shiny/Dash) that turn analysis into dashboards people actually use.
Worked with





I bring together climate science, public health, statistics, and machine learning to build tools that hold up in the real world, across four connected areas of practice:
Climate & environmental risk modeling
Hazard modeling and multi-hazard risk aggregation to support climate resilience planning.
Health & environmental data integration
Combining epidemiological, environmental, and geospatial data to support public health decisions.
Geospatial analysis & spatial ML
GIS analysis, remote sensing, and spatial statistics and machine learning.
Decision-support tools for public policy
Bayesian statistics and inference to quantify uncertainty and support robust decisions, delivered through reproducible analyses and interactive dashboards (Shiny, Dash).

Matías Poullain, MSc
I'm a biologist turned data scientist based in Buenos Aires, Argentina. After a biology degree focused on ecology and statistics and a Master's in Data Mining & Knowledge Discovery, I've spent the last several years building statistical and machine learning models, and geospatial analysis solutions for organizations spanning public health, climate policy, international development, and the agricultural industry. I also teach Bayesian Inference in a Master's program at the Universidad de Buenos Aires (UBA). I work fluently across Spanish, French, and English.
