Starting a research with a professor as a business professional
Many professors take a while to respond to emails. I would give it at least a week before you follow up with her.

When you do send a reminder, keep it brief and polite, and send it as a forward of your previous email, so she won't have to go searching for your other message. Reminding her of why you think the paper is valuable could be a good strategy--if you do it in a way that's not heavy-handed and that you think is true (i.e., it's actually of value to her career aside from another line on her CV).

It's always nice to give her multiple options for responding--you might include a line to the effect of, "If you'd prefer to chat about this over the phone, I'm happy to schedule a brief call at your convenience." Saves her time from having to compose a reply email.
