I have done a full year of research including the summer and I enjoyed my time there, but it's not something I am very interested in pursuing any further. I am just not too passionate about the research I was doing and would like to get some clinical experience instead. However, my PI loved having me in the lab and wants to keep me until I graduate. Is there a polite way to tell my PI that I would rather do something else other than the research? I also would like to eventually get a LOR from the PI, but I don't want to screw it up by leaving on a bad note. Or do you guys think I should just stay in the lab?
