Susan Conrad is a Professor of Applied Linguistics at Portland State University in Portland, Oregon, USA. Her work has focused on using corpus linguistics to describe and teach English grammar and discourse so that people can investigate language for themselves and understand how to make effective language choices in their own communication. She is co-author and co-editor of numerous books including The Cambridge Introduction to Applied Linguistics (2020), Register, Genre, and Style (2019/2009), Real Grammar (2009), and the Longman Grammar of Spoken and Written English (1999). With grants from the U.S. National Science Foundation, she started the Civil Engineering Writing Project, a multi-university project in which corpus linguists, engineering faculty, and engineers in industry collaborate to improve writing instruction for civil engineering students. The work has won two awards from the American Society for Engineering Education. Susan started her career teaching English in Africa and Asia.
