How I work

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).

About me

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.
