PeerJ Sections


PeerJ, the journal, is now divided into separate Sections by field.

Section Editors have oversight of their section to ensure the journal maintains a fair peer review process and the highest standards of scientific practice in their fields.

Within each Section, the Academic Editors regularly identify and highlight the most important new PeerJ publications in their field. Learn more & Meet the Section Editors.
