I want to do some research with a professor on campus, but I'm having a lot of trouble composing this e-mail. She sent me a long e-mail with stipulations for joining her lab and at the end it basically says "If you agree to all this, let me know and we'll set up a time and talk more about your project".

I'm having trouble saying "Yes, I agree to everything. However, I can't really meet until I get back to campus which is the week of the August 16th" in a professional manner.

Can you please help? Thank you.

Thank you for the email. I have read it and understand, and I agree to the stipulations you outlined. Can we meet the week of August 16th, when I return to campus?

Thank you so much.

Oh wow, thanks a lot. I guess I was looking for something longer, because her e-mail was a good 6 paragraphs or so.

When writing these sorts of e-mails, is there a trick to make it seem more formal and not informal?

Thanks a ton for the link, I really appreciate it!

You're very welcome.

Of course, I can help you compose a professional email response. Here's a suggested template:

Subject: Request for Research Opportunity Meeting

Dear Professor [Professor's Last Name],

I hope this email finds you well. Thank you for providing me with the comprehensive details and stipulations regarding joining your lab. After careful consideration, I am pleased to inform you that I am enthusiastic about the opportunity and I agree to all the conditions outlined in your email.

I am genuinely excited about discussing my project further and exploring the potential for collaboration. However, I regret to inform you that I am currently away from campus and will not be able to meet until the week of August 16th when I return. I hope this inconvenience does not cause any inconvenience in scheduling our meeting.

I would greatly appreciate it if we could schedule a time to meet and discuss the project in more detail at your convenience once I am back on campus. Please let me know of your preferred time and location so that we can set up a meeting that suits both of our schedules.

Thank you once again for considering my research interests and I look forward to speaking with you soon.

Best regards,
