Jat,
You might do a search of this forum with the search word miami. Another option is to find a local lupus support group members will often be honest about who is good and who isnt. Unfortunately the lupus associations tend to list any doctor who tells them that they specialize in lupus. Another option is to check the local teaching and research hospitals. Call the rheumatology department and ask which doctors specialize in lupus. Then take those names and google them to see what papers or research regarding lupus that they have been involved in.
Good luck,
Karen
