Piero was my TA for Intro to Comparative Politics and after the first discussion section, I was already looking forward to our next meeting. He was extremely knowledgeable about everything on the reading list and he did his best to help clarify many of my uncertainties about the course. He really took hold of the subject matter and was very focused on making sure we benefitted as much as possible from every section meeting. I often emailed him with questions and he always responded promptly and politely. Many people would probably agree that initially he seems somewhat arrogant, but donÂ’t be intimidated; after a while youÂ’ll find him to be a genuinely cool, down-to-earth kind of guy. His personality can be characterized by a mixture of brutal honesty and charming wit, making for really engaging and lively atmosphere. The only criticism I have is that he sometimes seemed to be in a hurry, and towards the end of the semester he seemed somewhat burned out. Sections were still informative, but not as upbeat. I imagine that juggling grad school courses and a teaching position simultaneously must be stressful, so I feel it would be imprudent to criticize too harshly. Perhaps under different circumstances those sections would have been more effective. Nonetheless, I would highly recommend taking PieroÂ’s sections because heÂ’s more reliable than most scholars IÂ’ve encountered at here at Columbia and he definitely knows what heÂ’s doing in the classroom.
