Comma placement after name

Question

I've always been confused where I would place a comma when introducing someone by name then detailing their place of work. For example:

The visiting professor is Dr. John Smith of the University of Chicago.

Would commas be needed in this instance and if so, where would I place them?

Answer 1

No need of Comma in your case:

Actually the first thing to know is that there are generally only few correct options:

one before and one after the name/title or to separate the elements in a series or a punctuation mark that separates words, clauses, or ideas within a sentence or no commas at all.

While a comma after the title may be correct on rare occasions (which don’t concern us here), a comma only before a name or title is wrong.

for example:

Incorrect:My friend Cleo, is a wonderful singer.

Correct:My friend Cleo is a wonderful singer.

Answer 2

A comma would be not be completely out of place if the sentence was worded: Dr. John Smith, of the University of Chicago, is the visiting professor.
