That's another possibility. I have a friend who is legally Mrs. X, but professionally is Prof. Y. There aren't any 'Paper Police' to enforce what name you use. Come to think, I could publish under "Indi Reloaded" if I really wanted to. LOL.
Dr. Loves Joy is actually a pretty good moniker, come to think.Tho it sounds more like a psych prof than a math one.
