Conference Speakers

The Conference Organizing Committee expects every speaker in a scheduled presentation to register and attend the conference.

If it becomes necessary for a speaker to cancel a presentation, he or she should try to find an alternate presenter immediately, preferably a co-author. Contact Miss Cindy Lu (This email address is being protected from spambots. You need JavaScript enabled to view it.) immediately with any change to a scheduled presentation.

A "no-show" or canceled presentation can cause serious inconvenience to the attendees and conference organizers. The committee thanks all speakers in advance for their compliance with this request.

We are not responsible for the safety and security of attendees’ computers. Do not leave laptop computers unattended.

Please remember to turn off cell phones, pagers, etc., during sessions.
