Unless there is a severe shortage of medical researchers these days that I’m unaware of, it would seem that for most medical research jobs, you would need a Ph.D. in a science subject matter. My father was a medical researcher, and even WITH a Ph.D. in biochemistry found it difficult to maintain the funding for his research. If, however, by doing medical research, you are talking about people who only support the researchers by washing dishes, feeding lab rats, or recording readings from machines, then I would imagine that you could do this with a bachelor’s degree in a science subject matter. Unless you are going to be brought into your mother’s lab just because you are a relative, you couldn’t do it with a degree in history or ceramics!

It is doubtful that some degrees would prepare you for what you wish to do. Research several types of jobs to see what the qualifications are. You might want to concentrate on the science area for your degree.
