I go to the University at Buffalo (UB) currently for undergrad and will be attending for my Master's in the fall. UB is a research university and if you attend, you have the chance to actually work in the labs with some really well known researchers in the field. I currently work in the Motor Speech Disorders Lab there and have had the opportunity to help with pilot studies and lots of TF32 analysis work. Everyone there is wonderful and there are specific courses dedicated to research (such as "Research Methods").
There is also a huge emphasis on EBP. I currently have a client with aphasia in the clinic and my supervisor would not let me finalize any short term goals without evidence that supports what I planned to do in therapy sessions. It's a great way to learn and so important for SLPs.
UB is also the highest ranked SLP school in New York state. I would truly recommend the program, I love it here! (Plus, Buffalo is an awesome city) I hope you find a program that suits your interests!
