• University of Alabama at Huntsville,
  
• University of Newcastle-upon-Tyne, UK - not far from where I live and I have met and been tutored by some of their graduates - very fine musicians they are too.
  
• University of Limerick in Ireland

• Royal Scottish Academy of Music and Dance
  

Of our flute/whistle tutors at Folkworks summer School in Durham this summer, one was Swedish with degree in Traditional Music from Stockholm and the other was Irish and is a tutor at University College Galway.

If you are prepared to travel, there looks to be plenty of choice.

Good Hunting.
