There is a lively graduate community, offering several opportunities to take part in book group discussions (many of which have included faculty members) and paper working groups.
USC has a chapter of Minorities And Philosophy, currently led by Maegan Fairchild. It hosts several events per year, including a speaker series and reading discussion group.
Reading groups are organized by interested students, and faculty members often participate. Recently, we have had reading groups on the following books:
There are also several working groups where students workshop papers at varying stages of completion. In addition to cohort working groups among each class, there are two very active topical working groups, one in Ethics & Value Theory, and one in Logic & Metaphysics.
The Speculative Society provides an informal forum for graduate students both to practice presenting papers to each other in the conference/colloquium format (i.e. fielding questions and objections), as well as to run new ideas past one another and receive suggestions for their further development. The group usually meets every two weeks during the semester, at a time chosen to accommodate as many graduate students' schedules as possible.
