E Shelley Reid
E. Shelley Reid, PhDereid1@gmu.edu
Director for Teaching Excellence, Stearns Center

Shelley has grown up in an extended family of teachers—including several college English professors as well as a middle school principal, a choir director, a medical school mentor, a gymnastics coach, a history teacher, a special education coordinator, and a high school counselor—so it’s not surprising that she frequently studies how both students and teachers learn. She is an associate professor in the Department of English, where she directed the composition program for ten years; taught undergraduate and graduate courses in writing, editing, and program administration; and helped create the doctoral program in Writing and Rhetoric.

She has recently published articles about how teaching assistants in composition programs learn to teach, how writing students engage in peer review activities, and how program leaders can assess student progress. She is interested more generally in questions of how learners transfer knowledge from one context to another, and how institutions shape the work of teachers and learners at all levels.

Fun facts: Charles has traveled a lot and loves to cook foods from all over the world—and if it’s not spicy, he doesn’t bother! He’d choose flight over invisibility, and if he were a tree he would be an oak so he could have all of the acorns he wanted (also squirrels are cool, even if they are rats with good fashion sense).
