Professional dilemma

Hi , I’m much interested into applied RL and looking for a job or a summer internship this summer , I’m a 3rd year undergrad at a tier 1 research institute . However my doubt is my main interest in rl is its ability to create greater impact , speaking about impact what I truly wanted was to use sample efficient rl and create an impact in sustainability and energy grid optimization but I think a greater application of RL that can cause impact would lie in Brain computer interface but it won’t be full RL , so tell me which firm I should go for most likely , I want impact more which is BCI but still not sure !
