We just uploaded interviews with three professors in our English Department:

Our Writing Consultants conducted these interviews. They may load slowly, as they are locally hosted. We have about 30 more in various fields. See the handbooks linked from this page:
Our long-term goal is to compile interviews for each handbook, as well as sample papers with commentary by the professors and writers (including some reflective “what if” remarks).
