Professor James is visiting next week. It'd be good if we could [meet up with/ meet] him and ask for his opinions about our research.

Which choice is correct?

Thanks in advance!

I'd choose "meet up with".

"Of course, we talk about meeting up, and that's a very common expression: in fact it's what we call a phrasal verb, but you can meet up, or you can meet up with somebody - that's always for social reasons and it involves getting together, usually then to do something else, and it may involve not two people, but a large group of people. So, at the end of an evening of doing something socially, somebody might say ‘when are we going to meet up again’?"
>meet up with - Informal. Don't say it in an exam.

Interesting, Clive.
Students: Are you brave enough to let our tutors analyse your pronunciation?

Generally speaking, here's how I see these.

meet up with - Informal. Don't say it in an exam.

meet with - Standard AmE.

meet - Standard. May sound too formal in certain contexts.

have a meeting with - Standard, OK in the right context.

Best wishes, Clive
