i suppose it also depends on the nature of your project and what exactly your role was in the lab. i suppose its better if you had a larger role organizing and setting up clinical trials in a medical research sense rather than doing something repetitive like PCR over and over again in a basic science setting. But then again, any kind of exposure is good. Its more important what you learned from the experience about science on a molecular level and about yourself. You dont necessarily have to do medical research on hot topics like the neurodegenerative diseases of aging or oncology or heart disease. The Ad coms might be more interested in a different kind of research that they dont get to hear about all that often. I did research in environmental microbiology (which has nothing to do with infectious disease or any fun pathology stuff), molecular genetics (drosophila stuff), i worked at a pharmaceutical company doing vaccine research (i get asked about this alot bc it was really cool and i got to wear a the whole pinstripe bunnysuit) and now i work on synapotgenesis in the hippocampus. anyway, any exposure you get is great, just get out there and find something you are passionate about! dont just do research bc its a hot topic for med school if you arent going to love the project because its not worth spending long hours in the lab sippin on that hate-orade!🙂 hope that helped, if u have any questions about research u can def PM me
