I am organizing the KIAS Geometry and Topology group seminar. In the group seminar, we usually have introductory talks. Also, I unregularly organize seminars that focus more on the current research in symplectic topology.  You can find a seminar schedule below. Also, for the group seminar, you can find more information, for example, the title and the abstract, on the KIAS Geometry and Topology group seminar homepage.
