Be sure to introduce yourself to the speakers upon their arrival.

2. If you encounter any issues during the conference, please don’t hesitate to ask our staff for assistance at the registration table.

3. Your main role will be to ensure that the session runs on time. Each speaker has 20 minutes including discussion or questions. If a speaker exceeds their allocated time, you should politely but firmly stop the presentation.

4. Before each speaker presents, your role will be to introduce them to the audience and remind everyone that all questions and interruptions should be reserved for the Q&A portion following the presentation. After each talk, thank the speaker, encourage applause, and open the floor to questions.
