Kaitlin Thaney is the Director of Mozillas Science Lab and an open science advocate. Her work in this space began with John Wilbanks building the science wing of Creative Commons (formerly known as Science Commons). Their focus was on crafting the infrastructure, policy and advocacy for Open Access and sharing data on the web.
Ask anyone in the open source science movement what it's all about, and you're likely to come back to the word that's right there in its name: "open." Open source science is all about open access. To research methods. To data. To scholarly publications.
