Whatishistoryanyway, that's super interesting! And the more I hear about Ohio State the more I can't believe I wasn't planning on applying there to begin with. There are a ton of sociology programs that fit my interests of course, but I am not interested in studying sociology. I have been "a historian" my whole life, and while my interests have strayed to areas that other disciplines have focused on more thoroughly, I think that's one of the more exciting things about studying race and incarceration historically, it's something that needs to be done and hasn't been to the same extent it has been studied in other fields.
At UCLA, I am interested in working with Scot Brown (who you may be interested in as well), Eric Avila (more urban), and Robin Kelley. At Michigan, it would be foremost Matt Countryman but also Stephen Berry, and Penn would be Sugrue and Katz. UIC has quite a few profs, and an entire Ph.D track devoted to "Work, Race and Gender in the Urban World." (My interests are still centrally Urban history, and that has effected the places I am planning on applying to).
Because, as you guys have pointed out, this work is done more often in other disciplines, I am primarily looking at working with people in my broader fields of interest then attempting to find historians working on these same issues, because there aren't very many in the field. I don't know if I should rethink this approach, but that is how I am going about it thus far.
