Hello, I'm a MSI4 whos doing a little planning ahead for MSM. My school has a research block in 4th year so it would make sense for me to try to seek research opportunities for the sub specialty I want as I am thinking of IM. Since medicine subspecialties are much smaller field I assume the "who you know" factor plays into it a lot more than matching to IM. I found two potential PIs that I am interested in. One is a young staff who is extremely qualified, hired on as an associate head role at a very young age and leading trials. Other one is one of the most influential individual in the department, world-class leader whos research I may be slightly less interested in.
Young staff: probably more productive given his point in career, probably will care about me more & have more time to support me, but will not have been in the department/field long enough for him to sway the departments (esp OOP programs) for me.
Older staff: probably less productive and not support me in research as much as I will need/want, but his opinion will matter a lot more in this subspecialty across the country.
For those wiser than me that have gone through this game, is who you know as big of a factor as I'm making it out to be? I already have done a bit of research in this field and have few 1st author publications. At this point is it wiser to find the biggest name that can support me?
