Seminar
 
The CGGC holds a weekly seminar which provides a forum for local experts and guests from abroad to present their research. Most of the CGGC graduate students present the results of their MSc or PhD research in this seminar, and there is a sprinkling of industrial presentations. A light lunch is served.
Coordinated by (and address for all complaints) Gill Barequet.
Usually held on Sunday 1:00 pm in Taub 337.
