Office: SAL 302
Office Hours (5/19/2022 - 7/28/2022): Tue/Thu 3:00pm - 4:00pm - Office hours will be held in Zoom meetings.
I will have to limit the time for each student to be 15 minutes max to give other students a chance to get in.
If my office hour Zoom meeting is running but if you cannot see me, then I must be talking to a student in a breakout room.
Zoom meeting is first-come-first-serve and sometimes there may be quite a few students waiting in line.
Therefore, there is always a possibility that by the time the office hour ends, you are still waiting for your turn.
The best time and place to ask me questions is during a "secondary live lecture" where you can ask for a breakout room
and such a lecture is not shared with another class that I'm teaching.
It may be best to e-mail your questions to me or post your questions to the class discussion forum.
As promised in Lecture 1 of all my classes, I will answer every e-mail question within 24 hours
(if the e-mail is a private e-mail, i.e., to me only and not posted to an online discussion forum).
Phone: (213) 821-4222

Please do not leave a message.)
