I have a BS in cognitive science and previous experience as a research assistant in a neuroimaging lab and really enjoyed that area of research (functional connectivity, default network, DTI, fMRI analysis in SPM, etc.). I want to advance my career but don't think a PhD is the best fit for me. Is there a way I can continue this work at a higher-level? I worry that there's either work for entry-level RAs only a few years out of college, graduate students working on their PhD degree, or bio-statisticians, but not someone with more years of experience in the field. If I get a masters degree, I'm not sure that will open up more opportunities either. If I become a clinical coordinator or nurse researcher, I fear that I won't be able to be involved in that kind of analysis, but will be more on the management/regulatory side of clinical trials. Any insight would be appreciated.
