OP:
A student read your question and asked me the same -- I figured I'd reply to yours as well (though I'm generally not sure if it's cool for professors to post here so forgive me if not). Your post signals two things -- one, an interest in incarceration and health and two, an interest in policy. It sounds to me more like you care more about the former, not getting a policy degree per se, but I've listed a bunch of schools below to check out.
There are a number of sociology programs with interests in incarceration and health -- Penn Sociology (Schnittker), MN (Uggen), UW, Cornell, Harvard. In crim, UCI, Rutgers, John Jay, FSU. UCI also has an MA in policy that is headed by one of their crim faculty (Tita) so you could probably access that in CLS. Cinci is more CJ-corrections and yes has some people doing CJ policy. Maryland also has a number of faculty trained in policy programs and several faculty with incarceration interests. If you want a policy degree, look at Carnegie Mellon (Nagin) and Cornell PAM (Wildeman, does a lot of work on health) but these two programs are very different (George Mason also). Also check out Penn State. For all of these, it's a matter of taste (soc, crim, or policy), what job you want when you get done, and yes indeed you should check out faculty in each program, read some of their stuff, and figure out what excites you the most. Of course, you've missed all the deadlines for these places this year but this should get you going for next year. Hope this helps and good luck!
