PhD question

Before I get into my question, let me say I tried to find the appropriate area to place a question related to PhD nursing, but was unable to locate it. If someone wants to move this post to the correct area, if there is one, please be my guest. I was thinking "specialties", but didn't see anything :/ I have been doing research concerning different programs and areas of focus and I have a few interests, but I've seen the area of pharmacology, more of less, as areas of research for many faculty members at different programs. Pharmacology was my favorite class in undergrad and I've always had an interest in teaching, so this appeals to me on different levels. I am wondering, what other career options does one have with a PhD who made their focus or conducted research in pharmacology? A lof of the other research interests by current faculty at these different institutions have obvious practical applications, along with teaching, but this one is lost on me a bit. I have done searches online on other sites and here, but couldn't seem to find much. Thanks!
