In between classes, my professors generally hole up in their offices and run their office hours, which means they grade tests and papers, meet with students when/if they come by (for help with papers, coursework, or general advice), and work on whatever research/junk they might be involved in. If this professor is a main character, you might want to give some thought to what his interests are in that respect (for example: I'm in English and Classics, and one of my professors might be sitting in their office looking over Shakespearean plays to write a book on the role of crossdressing in comedies).
As for an average day at university...um? Campus is full of people, outside smoking or walking between classes, often with their coffee; students flush out of classrooms in torrents at certain times when courses get out...really depends on what kind of details you need, I guess.
