Haude is a linguist associated with the Documentation of Endangered Languages project from Germany. She is part of a new generation of linguistic scholars who are describing and analyzing the array of mutually unintelligible languages of eastern Bolivia and Southwestern Brazil. Among other specialties, she has written the definitive account of the Movima language. The area made up of Mojos and the part of Brazil just to the northeast, across the Itenez or Guaporé River, is unsurpassed in language diversity. Only the interior of New Guinea has the same number of distinct languages in a small area. Haude and others are conducting excellent research, and the first linguistic research of any kind in the area in decades.
