<p>So if I am doing research with John Doe, should I refer to him as
John C. Doe (CC 72)
in order to indicate that he is an alum... or is that terribly absurd? lol</p>
<p>P.S. He/She's pretty famous, but less famous than someone like Madeleine Albright.</p>
<p>If he's so famous you won't have to indicate that he's alumni. Just make it clear that you are talking about that famous person and not someone who just happens to have the same name as that famous person.</p>
