Grover has, at various times on Sesame Street and in books, donned the mortar cap and gown of Professor Grover, his lecturer alter-ego. In one such appearance, Grover explains how to take a bath, doing so while still wearing his scholar's cap. He has also done so for public appearances. On Feb. 8, 2005, Professor Grover visited Harvard University for a news conference announcing a new HGSE course, "Informal Learning for Children."
Professor Grover is the central character in the Sesame Subjects book series, in which he teaches Elmo about different subjects, and features in some other book appearances as well. He has also, on occasion, tweeted from Sesame Street's Twitter account.
