Dennis Baron teaches and writes about the English language and the technologies of communication. In addition to his scholarly publications, he writes frequently on language and technology issues in the news, and his essays have appeared in the New York Times, the Washington Post, the Chicago Tribune, and many other papers; he is regularly consulted by journalists and has appeared on CNN, NPR, the BBC, the Voice of America, and the CBC -- he's even discussed the changing English language on Joan Rivers' radio show. He's interested in language and the law, has consulted in a number of legal cases, and was asked by the Washington, DC, attorney general to write "the Linguists' Brief," presenting a grammatical and semantic analysis of the Second Amendment in the Supreme Court case Heller v. District of Columbia. That amicus brief was cited in oral argument and in both the majority and minority opinions.
