Market/Design Research?

Could someone tell me what are some good schools to learn market research or design research? I have been doing ID for 5 years and all of my projects so far focused very little on research. I am unsatisfied with my career so I am thinking about going back to school to study market or design research. My goal is to be in a position where I can spend more time studying users of products (the market) and use my ID skills to influence company’s product line. I have 2 bachelor degrees and I’d like to get a masters. Thanks for any suggestions or advice!

Graduate programs are all about research. Just check out the schools that offer advanced degrees. (There is a school page on core77.)
