Don’t worry about it, take it a step at a time. Your priority now is relaxing until you start the school year, then to worry about acclimating to medical school. Around winter time you could start poking around for faculty conducting research to see if they’d take you for either the 1) spring semester if you’re super duper great at balancing your work or 2) the summer for a quick summer position.
Personally, I wanted one of those rubbish first author pubs so I sought out someone that already had a boat load of data and just wanted their data analyzed + transcript written. This summer I’m doing exactly that - no lab time which is great for me, full remote, just analyzing this dude’s data with hopes on writing majority of the paper + quick first co-author.
if you want lab experience or something more longitudinal, I’d look for someone who wants that kind of work done, then you could drag it out into your 2nd year and you’re in like Flinn.
