Does anyone know of any professors or ethnomusicology departments that research instrumental music and dance from both Nordic countries and North America?

I'm interested in conducting graduate research on the evolution of dance music traditions in Baltoscandia, the British Isles, and North America, and the impact that these traditions have on rural communities in the present day.

Are any of you aware of any ethnomusicology departments with professors that are interested in this kind of research? Thanks in advance.
