This document summarizes a workshop on written communications for researchers. The workshop aims to help participants improve the clarity, structure, and quality of their writing. It will explore why most written communication fails to engage readers, and how to write in a reader-focused way using plain language principles. Techniques covered include targeting the reader, using logical structure and signposting, calculating readability scores, and avoiding common grammar mistakes. Participants will create a personal action plan to apply techniques to their own writing.
