I’m a data scientist based in Barcelona, working mostly on health-adjacent problems, mixing environmental and omics data.

I use this site as a sort of public portfolio, a place to share projects, writing, publications, and whatever I’m building or thinking about lately.

Check out my web CV or my LinkedIn profile for a full professional background.

Data Science

Applied ML/AI, time series, spatial analysis, statistics, and data visualization

Metagenomics, sequence analysis, reproducible pipelines

Packages, web tools, APIs, research workflows, data engineering

Email is the simplest route for collaborations, research questions, or anything you might want to reach out about.

A collection of mostly open-source software projects, repositories, and code snippets that I have built over the years.

Published blog posts with a mix of technical and non-technical content, from research notes to coding experiments and reproducible notebooks.
