International Security Studies at Yale runs a weekly series of talks by graduate students and faculty from many different departments called the Colloquium in International History and Security. Speakers normally present for around 30 minutes, and then take questions and lead discussion for another 30-45 minutes, in seminar format. The talks are held on Tuesdays, at 11:45 a.m. during term. These talks cover a wide variety of subjects. Speakers often use the series to present work in progress, or to try out a possible job talk or a draft conference paper.
