I have a PhD in modern European history, and am a former faculty adviser to undergraduate and graduate student.  I have published a book and several articles for peer-reviewed journals.  I believe in writing with my readers in mind, and I bring the same attitude to my editing.   My editing emphasized clarity, flow, and conciseness.  When necessary, I ask the kind of questions that might occur to the target reader so that the final product is reader-friendly, persuasive, and professional.
