Looking for a sociologist type on a TV show

The academic job market may be bad but how many sociology graduate students might consider a casting call? Here is one that might fit:

Casting an archeologist, anthropologist, sociologist, scientist or the like; who can investigate extraordinary occurrences that some claim to be signs of the Apocalypse. History buff a MUST, with personality plus!!

This is quite a wide range of possible disciplines. How exactly would one play a sociologist in this situation – spout classical theory? I can’t remember ever seeing a sociologist portrayed on TV or in a movie.

(The firm that put out the casting call, Bel-Espirit Creative, is led by a woman with a background in sociology:

Loreen has a B.S. in Sociology from the University of Oregon, where she was a DJ and host of several shows on KWVA, the University’s campus radio station. Since founding Bel-Esprit Creative, she’s worked in music production for tv, audio post-production, art direction for TV, and script writing for radio. In addition, Loreen taught a class on Reality TV at New York Film Academy. Prior to working in entertainment, she was a social studies middle school teacher for at-risk students.

I wonder if this sociology background has influenced other casting/talent decisions.)
