Open science is the practice of science where data, lab notes, publications, etc. are made publicly available to enable reuse, redistribution, and reproducibility of all parts of the research process. Such practices encourage collaborations and make science more efficient. Open is the way of doing science for the leaders of tomorrow. As a part of Life Science Zurich, we at OILS help life scientists understand what open science is to them and, most importantly, how to practice open science as part of their research routines via public discussions, workshops, courses, and our annual Open Innovation in Life Sciences conference. Everything we do is motivated by early career life scientists and supported by leaders in open science.
