The purpose of the course is to provide a forum for PhD students to exchange their research ideas, as well as to provide contact to other students and scholars in the same research area from outside the university. Senior PhD students in our institute are required to present their research work about once per academic year. We will also invite distinguished scholars to the forum to share their research experiences with our students. Each registered student will need to write a short comment on some selected presentations, thereby to learn how to appreciate and criticize other peoples work.
