Corvallis is a very nice barely-a-town, lol, but that (combined with the competitiveness of WUE at Oregon State) was why I countered by suggesting the Portland State + OHSU public health program, where WUE would be assured and students truly participate in urban public health initiatives.
An aside re: AustenNut’s suggestion of UTDallas - I’m not sure what the cost/aid picture is like there for non-NMF OOS students, but it certainly checks the major city box (albeit on the outskirts) and it would be a great choice for CogSci - perhaps the most robust multi-track CogSci program outside of UCSD. And there’s an undergrad public health major too. So, a nice fit in several ways, if the money and geography would work.
Anyhoo, a ton of good suggestions have been made; we’re probably due for some feedback from the OP on which ones do and don’t appeal, and why, before we can be of much more help.
