I hope this message finds you well.

My name is Dr. Eunhye Baek from Tsinghua University. 

I'm interested in participating in this year's workshop, and have just registered for your mailing list.

I'd like to ask whether registration for this year is already closed. 

If so, I was wondering whether there might still be any available slots.

Thank you very much.

Best regards,

Eunhye
