I am deciding between a few programs now. They are quite varied in their focus. One university has one prof that I would want to work with who studies neural regeneration in C. elegans. I wouldn't say neurobio is my main interest, but I felt like I really clicked with this prof when I met him. His view of how research works and how it relates to society aligns with mine.
My question is: would my career be pigeonholed to working in neuroscience? Could I pivot hard after PhD to working on something quite different? Say, evo devo using mice, molecular bio of DNA replication, etc? I know that I value finding the right mentor over the specific sub-field. I'm not sure that I would be happy pursuing neuroscience for the rest of my life though. Thanks!
