All materials are published as Open Educational Resources, free and reusable by anyone.

Rigor

Content is reviewed and updated continuously to offer clear, well-grounded explanations.

Hands-on learning

Every topic comes with solved exercises and examples using real data to learn by doing.

Reproducible science

I support Reproducible Science: I try to make sure that the decisions, design, methodology, data collection and procedures of my studies are clear and transparent enough to be replicated.
