Aliasing hakase_(nichijou) -> professor_(nichijou).
Reason: It's a title, not a name. We call the 博士 from To Aru Majutsu no Index and the 博士 from Disgaea Professor (Index) and Professor (Disgaea).
Or maybe the tag should be professor shinonome, since according to the Nichijou wiki, her surname's Shinonome.
