Hi there,
You need to have a masters or doctorate to teach in most medical schools. Some disciplines are only at the masters level and thus a masters is enough. Most medical schools will not allow you to attain the rank of professor without a doctorate (medicine or philosophy).
There may be some with both MDs and PhDs, but most will have one or the other. Which one they have depends on the department: most of your biochemists will have PhDs, but most of your surgeons will have MDs. It seems that pathology is a dept. that tends to have a lot of MD/PhDs in it.
I think the main determinate of whether the prof is MD or PhD is whether the the subject is a basic or a clinical science, although there is still variation.
I'm currently working at UTMB. My PI/co-director has a PhD and teaches in the medical school, as well as one of our post-docs (PhD). The other co-director is an MD and is full time faculty in the med school in addition to doing some research.
I dont think its exclusionary, but i think you need to have at least an MD or PhD (or equivalent) in order to teach.
Yeah, the PI in my lab teaches the Pharmacology section, and she's a PhD. I think basic science areas are often PhDs since they have a more fundamental working knowledge of it, while the more practical applications are MDs. Just a guess.
