question about urban planning/design from the usa

Hello.  I am writing from the US.  My boyfriend has received an Eisenhower fellowship to study in Germany and Spain in the late spring for two months - see link below.  He is the Director of the Urban Design center in Raleigh and is looking to set appointments with folks in similar fields to learn more about the European models of design and sustainability.  

Can you suggest anyone that I might contact that could meet with him while he is there?  It would be much appreciated.

Thank you!
