While introducing someone, we use commas.
· This is Jane, my sister.
· The distinguished scientist, Mr. Stephen, of AKL University, will be addressing the crowd tomorrow.
In the second sentence, the comma before and after the name indicates we are talking about a specific scientist of AKL University. The comma after the name also tells us that the information after the name is essential to identify the person.
Doesn't the comma before the title of the University define it as non-essential not essential to identify the person in this example?
Not least because there would likely be many distinguished scientists within any given University but were talking about a specific one.
