Editorial team

How we work:

Science editors identify trending news and claims according to their influence on social media and the quantity or degree of scientific evidence within the reporting. Once an article or claim is selected for review, one editor leads the fact-checking effort by contacting relevant experts, reading and summarizing the scientific literature on the topic, and writing a draft of the review. At least one other editor reviews the draft, challenges the claims, and pinpoints where additional clarity and references are needed. Challenging questions are decided by the director.


Emmanuel Vincent

Founder & Director

Emmanuel completed a PhD at the University Pierre et Marie Curie (Paris, France) and a postdoctoral fellowship at the Massachusetts Institute of Technology (MIT; Cambridge, USA), studying how the Ocean controls Hurricane intensity and how Hurricane can in turn influence the climate via their interaction with the Ocean.
He launched Science Feedback to help the scientific community play a leading role in providing the public with accurate information on scientific topics.
