I have a very strong interest in optics with biomedical applications, and I have been noticing this field growing over the last few years; however, the number of programs seem very limited. The big programs are University of Central Florida, University of Rochester, and University of Arizona. I do not want to limit myself to applying to three programs. What other candidates exist and currently growing? Does anyone know if the Fitzpatrick institute at Duke has ambitious future plans? I ask about Duke mostly due to their strong link in medicine.
