<p>The MDs or MD/PhD Profs in my alma mater in NY not only taught med students and grad students but were also involved in research activities.</p>
<p>They all continue to have their own labs where they conduct fairly high level research in various depts such as Pharmacology, Pathology, Physiology, Genetics, and Public Health to name a few. They generally have MD, PhD, and MD/PhD students who work toward their dissertations.</p>
<p>These Profs generally teach a couple of courses/semester and spend most of their time in research labs with occasional sabbaticals.</p>
