He is (was) a DADA teacher and we have been told that Dementors are 
dark creatures, even in league with LV before his fall from power, so 
it is safe to presume they have something to do with the dark arts. 
Surely it is part of Lupin's area of expertise to know how to defeat 
them and teach it to other people? Just as it is NOT part of 
McGonagall's area it is part of his.
