Do you plan to present a paper at a conference in Germany? Or even worse, are you applying for a job there? Then you'd be better be careful what you call yourself. A Washington Post Article that came out today states, "Americans with PhDs beware: Telling people in Germany that you're a doctor could land you in jail." Apparently no one outside of the European Union can call herself "Dr.," even if she has worked at the Max Planck Institute for 10 years and has a Ph.D. from an elite university in the States. So, caveat scholasticus (ok, I don't speak Latin, but that's my best guess at "Scholar, beware"). Or perhaps I should say, Herr oder Frau Doktor, seien Sie vorsichtig (ok, I don't speak German, either.) But consider yourself warned.
