Studied science and technology and interested in policy research?

Hi everyone,

My education goes like this. Masters in Physics and Materials Science. I realized that I can excel in policy research rather than the laboratory research, especially related to energy and space. As I looked into the profiles of the grad students, most of them have a solid background in law. I am a science student. I don’t have a law degree. Need help.

Would it be possible to get into a grad school?
