What does resident mean in title like resident mathematician?
And what are the main subjects where resident is attached to a title? For example, does a resident statistician exist? Or a resident medieval historian?
What are the place where the mathematician resides? I think they are not universities but maybe hospitals or museums, am I correct?
For example, from Writing a successful thesis or dissertation: Tips and strategies for students in the social and behavioral sciences by Fred C. Lunenburg and Beverly J. Irby:
Ideally, commitee members should supplement your chair's expertise. If your study requires complex statistical procedures and your chair is not a statistician, you may want to add to your commitee a faculty member who teaches your department's statistics courses. We call this person a resident statistician.
