I understand that a somewhat similar question has been asked before, but my parameters here are slightly different. Essentially, I have been emailing a professor since early April about joining their lab. They have responded and inquired what sort of projects I would be interested in. They also remarked that they would be interested in meeting after the semester is over. Well, after final grades were input I sent an email and... no dice after two-ish weeks. This is no surprise, given that I know a student who got a response from them months after sending an email. The thing is, I am trying to join their project over the summer and well, precious summer days are about to start passing pretty fast.
In summary, I am moving close to campus next week, and I am wondering if it would be rude or brutish to go to their office location physically to follow up. Is this a bad idea? The difference between this situation and the last person who asked is that this is during summer and COVID times. I also just finished my freshman year if that matters.
EDIT: as a corollary, I could also try calling the office. Though that almost seems more incessant than showing up in my opinion. Thoughts?
