I don't really have any experience in your subject area, but I had fun finding scholars in my field by going back and looking at the authors of the major articles I've worked with. I looked up the article author(s) and also some of the authors of the main works mentioned in the footnotes/endnotes. It definitely wasn't foolproof, but it was a good way to get me to look at institutions that I wouldn't necessarily have before, or universities that I knew had someone who wrote things I was interested in.
