She can read Nahuatl, she makes the indigenous people of Peru and Mexico exciting. You can go into her lecture exhausted and go out exhilarated. she obviously prepares a ton for lecture: they directly correspond to the readings, and she makes sure they are organized. She's self-deprecating about being Italian and having to work in English. It was an awesome class, she was more about themes than dates and specific names. Examples of the themes in individual case studies are stressed in the class. Plus, she actually uses interesting art and photos for lecture.
You might not want to take her, though, if you love European history; she admits that it's not her field, and tends to gloss over European events that are probably important...like Napoleon.
