Doing research and then analyzing and summarizing your findings in a scientific journal article, a grant application, a PhD dissertation, or an academic monograph can be a complex, daunting task. Add to this the pressure of meeting an urgent publication deadline, following an elaborate set of guidelines for authors, or writing in English if it is not your first language, and it becomes easier to overlook language issues that may confuse your readers and detract from the quality of your research. Problems with the language of your manuscript can delay or even prevent you from publishing. Yet, a professional editor can help with this by pointing out issues you may not have noticed and by suggesting changes that clarify your message.
