Hi wiboy,
Congrats on your current or future acceptance to med school. You are right, research is important for getting residencies in some of the very competetive fields (orthopedic surgery, ENT, opthomology, etc.) and very helpful in competing for spots in the most prestigious residency programs in any specialty.
I don't fully understand your question. I think you are asking if it is neccesary of very helpful to continue cranking out pubs from your current lab even though you don't really want to be there anymore. I would say no. You have a VERY impressive undergraduate research record. My suggestion would be that if there is a particular medical specialty that you are interested in, find a faculty member at your new medical school who is doing research in that area. My impression is that if you want to go into orthopedic surgery, the residency programs want to see some research relevant to orthopedic surgery and are less impressed by fruit flies and the like. I am sure the same goes for other competetive specialties.
Hope this helps?
