The What is... Graduate Seminar (TWIGS)
The What Is... Graduate Seminar (TWIGS) was originally founded by Farshid Hajir in 2002 as a way for graduate students to learn about faculty research interests in an accessible forum.
Talks will be given by Department faculty on topics related to their research. The goal is for the talks to be as accessible as possible to all students in the Department. We encourage all graduate students (including incoming students) to attend as regularly as they are able.
