Basically title. I'm in a lab right now, but I'll be home (more than 2 hours away) for the summer. I'm from a pretty large city with several universities, would it be inappropriate to basically cold email profs and ask about joining their labs for the summer if I'm not really connected to the institution? When I was in high school, I did briefly spend some time in one of the labs at one of these universities, but other than that I really don't have any connection to it. I'd love a spot as a research assistant, but honestly just volunteering my time would be more than worthwhile. I'm honestly not really doing this "for premed"; so far I've really enjoyed my time in lab and I want to explore some other fields.
