Two reasons:
The first is just to genuinely increase my foundation of knowledge in those two subjects. I have always just learned what I needed to as I went in those areas. I figure I could be a more productive research/innovator if I had a stronger foundation in those two subjects (although feel free to call me on that if you think differently.)
Second, I come from a very blue-collar program (we cover the only two level-1 hospitals in the city with only 4 residents a year). We operate a ton but our research infrastructure is poor. I know I won't be able to compete with an applicant who has the institutional infrastructure to author many papers a year. Our last few residents who went trauma (who were very well trained and highly competent) didn't get interviews at the big-time programs like Harborview and Shock. I think part of that is that we don't have big names writing our letters. Also, even our highest producing research resident here is only pumping out a couple of papers a year. I figure some more academic credentialing could increase my chances of those highly prestigious places being interested in me. Ideally, I would be able to go to conferences and network but in the age of COVID, that seems less and less likely.
Thoughts?
