Editors & consultants

Cofactor is run by Anna Sharman together with a network of over 50 highly experienced freelance editors. As well as having their own scientific and editorial expertise, editors are trained by Cofactor to understand what journals want in a research paper.

When your paper is checked or edited by a Cofactor editor, you will be getting the expertise of someone with subject knowledge and experience at working with journal papers. Many of our editors have a PhD.
