Why we ask

Everything on quantitative.bio — the books, the tutorials, the workshop materials — is free to read and reuse. We’d like to keep it that way for the next biologist, and the one after that. The Circle is how we keep the path open: people who’ve walked it before help the next person along, in whatever way they can.

None of the options below are obligatory. Read for free, learn what you need, and if it’s genuinely helped, pick whichever way of giving back fits your moment.

Ways to give back

Buy a book

The R Crash Course series is published in print and ePub through DP Press. Buying a copy — for yourself, a student, or a colleague who’s about to bounce off another tutorial — is the most direct way to support the project.

More titles in the series are on the way. We’ll add them here as they ship.

Contribute new content

A worked example from your own research? A chapter idea? A typo you keep tripping over? The Circle includes content contribution. Tell us what you’d like to see — or what you’d like to write.

Host or co-host a workshop

The AZ2CH workshop format adapts to conferences, departments, and lab groups. If you’d like to host one at your institution — or co-teach one with us — we’d love to hear from you.

Already in the Circle

The current quantitative.bio curriculum exists because dozens of students, alumni, and undergraduate researchers tested chapters, hunted typos, and built the workflows the books grew out of. Their names are listed on the Meet the team section of the homepage and on EcoEvoGeno.org/people.html. Today’s student becomes tomorrow’s contributor — that’s how the Circle works.
