Can an economist be an RA

I’m currently facing a dilemma between two universities: Drexel University and Thomas Jefferson University.

Thomas Jefferson is more focused on healthcare but doesn’t have a notable economics department. The only economics-related degree they offer is in applied health outcomes.
On the other hand, Drexel doesn’t have a strong focus on health specifically but does offer degrees in the general sciences like Biochemistry, Biomedical Engineering, etc., along with a solid Economics department and a Health degree.

Right now, I know I’m passionate about biotech, and I’ve recently been learning more about regulatory affairs.
My question is:
Can a health economist—or even a general economist—transition into a regulatory affairs role? Do I need to go the clinical or health science route?

Wouldn’t strong networking, gaining industry experience, and building up my RAPS portfolio be enough to get me there?
