If you’re interested in global studies (somewhat related to your interests I think), check out the Buffet Institute (http://buffett.northwestern.edu/). NU recently got $100M from Warren Buffet’s sister to beef up this institute.
Also check out NU’s MMSS program and Kellogg Certificate programs…both programs have very strong job/grad school placement records: (http://www.mmss.northwestern.edu/undergraduate/employment-placements.html)
