Do not refer to faculty members as professors unless they have earned that academic rank. Any variations of professor, such as associate professor or professor emeritus, should be used. The preferred use is to put the title after someone’s name: Casey Smith, an associate professor at the Missouri School of Journalism.
Non-tenured track faculty members are typically identified as “teaching” or “research” professors. Example: Jones is an assistant teaching professor in the College of Engineering.
Adjunct faculty are professors and instructors employed by the university who are neither tenured nor in tenure-track positions.
