I currently have a BSc. in Environmental Science and would like to go back for a biology focused PhD in the next few years. I keep seeing the recommendation that having a good research fit will be important to potentially being admitted.
My question is, how do I go about getting research experience in biology when my degree is in something unrelated?
Answers to the question on How to gain research experience after master program? suggest various possible research opportunities. I've looked at jobs and volunteer opportunities like those, but I'm not sure I'm qualified for them. Even when I find a job that says ‘no experience necessary’, they are still asking for a biology degree. Presumably anyone with one would have had some experience in a biology lab, whereas most of my lab experience is in geology labs.
I don't understand why they would take someone without a relevant degree or experience (even if it's in-class experience) over interns, under/grad students, various types of volunteers with relevant degrees. Without understanding that, I'm not sure how to approach people about these potential opportunities.
How can I identify research opportunities I am qualified for, and position myself as a competitive candidate for these positions, when I don't have a relevant degree or experience in the field?
