I have a Masters's degree in Communications Engineering. Right now I have been working on protein analysis, molecular dynamics, Monte Carlo, and neural networks since February 2021. I studied these topics myself while working with a research professor as those were neither part of my bachelor's nor master's. I am sending a jointly(3 persons: me, the PI, and one of the Ph.D. students under the PI) authored paper to a journal called Biomolecules for publication on Monday (11 April 2022).
I am searching FindAPhD and I am not finding enough advertisements on these topics. It looks like it is too much niche area of research.
Is having a different academic background than the research experience detrimental to the career?
