== Oxford academic == 

 As far as I can tell, he has never held any appointment at the University of Oxford and so ought not to be in . This detailed profile doesn't mention teaching at Oxford (although it does mention Cambridge, Harvard, Yale and Cornell). He gave Oxford's 2014 African Studies Annual Lecture  but that's not enough to put him within the category (because people aren't categorised according to venues or institutions at which they've given a lecture). If no-one can find something to show that he has held an academic appointment at Oxford then I'll remove the category again.
