Well, I’m a bit biased, but I highly recommend University of Maryland. Rebecca Anstine Smith is the teacher there, and Alice Chalifoux gives monthly lessons to all harp students.
On the other coast is the University of Washington, which I know has both marine biology and harp (Pamela Vokolek).
Have you looked into U of Toronto with Judy Loman?
Look into Boston University…GRRREAT Harp Program including Lucille Lawrence as head of staff (who was once married to Carlos Salzedo). Also, try http://www.Collegeboard.org for an advanced search of all the programs you want…great site.
For harp or music generally plus something else, try the University of Cincinnati. The College Conservatory of Music was an independant
