Chris Hartgerink (they/them; @chartgerink) is a generalist: part researcher, part statistician, part software programmer, part businessperson.

Starting in social psychology under who later became known as the biggest known psychology fraud, they subsequently focused on meta-research and ways to improve the sustainability of research. They were a Mozilla Open Science Fellow and a Shuttleworth Fellow.

In 2019, they founded Liberate Science GmbH after leaving academia. A mentor called them a "voice of reason" while also being a "system challenger." Their philosophy of open is one of equity and power distribution, instead of accumulation. It is relentlessly radical, which does not aim to burn systems down, but to (out)grow old ones. This philosophy is captured by the Liberate Science Manifesto.
