In this podcast, we get to know Marcio van Muehlen, a biological engineer from MIT turned entrepreneur & product manager in Silicon Valley. He was working on cancer diagnostics through blood sampling and wanted to have better access to the work from other scientists in the field. There he recognized early on that we need a github for science and published a widely referenced article on it in 2011. We talk about why we need a github for science, what has happened since he wrote the article and what is still preventing us from having more open collaboration.
