There are university master degrees for UI/UX in the states?
Don't they have that everywhere? The Human Computer Interaction deparment at the (European) university I went have both Master and PhD students and do all kinds of UI and UX related research.
They are slowly popping. The two major ones are probably CMU's MHCI and University of Washington's HCI+D. I don't know about Washington, but CMU also has a PhD program in HCI.
