Most likely will depend on the individual PD, and their respective specialty. If you have specific programs in mind at this point, take a look at their websites and see if they have any information about the research that their residents/faculty have conducted.
Anecdotally, I had a variety of different research projects/publications and it did not negatively impact me during interviews/Match.
Hi, just wondering if having many different types of pubs (a few basic science, a few public health, etc) is indicative to potential residencies of lack of focus. I took a few years off before M1 and did research during that time. Probably aiming for mid-tier Peds if that affects anything.
most likely not, especially if these research was published before you even matriculate med school. PDs don’t expect you to decide on a specialty before med school starts.
