Dear committee,

Thank you for agreeing to being a member of my PhD committee.
I’d like to schedule my first committee meeting, which I’ll use to briefly introduce myself, past research and current research as well as outline completed and ongoing courses. 
The meeting will be held via zoom.

Please fill out the WhenIsGood poll using the following link. I picked the last week of October, please let me know if it doesn't work for you.

Let me know if you have any questions.

Best,
XXX
