I'm guessing you are looking for people right out of graduate school?

These people will be hard to find, if they're under 40. What's the old saying, in architecture you don't really hit your peak until you are in your 60;s? Architects are late bloomers?

With that said, try a guy named Quilan Riano. I think he was an editor on this site, and an architect. I could be wrong, after all I don't even know his age. I don't even think I'm spelling his name right.

Did you look at the previous year's winner's of the YAProgram at the Moma PS1?

michael meredith?

he's probably under 40, correct?

and the SERVO folks?

I don't know if Michael A. Fox is still under 40, but if not, he can't be too much older than it either. foxlin.com

And his partner on the book, Interactive Architecture, Miles Kemp, is definitely under 40 and looks to be doing some interesting things

Neri Oxman, too

I've recommended this group before: NC Office out of Miami

is that a serious submission mdler? ps, we need to grab drinks again

Look at the main design schools out there and ask them if they have young professors which you could highlight in your research. I think that's where you'll find your 40 and younger group.

interestingly the Guardian in the UK did a survey of architects under 30 (some not yet registered but still practising in that mode - one way or another).

PbElemental is doing more work than anyone else out there right now

Maybe you should broaden your search to include Europe. I think they'll be easier targets to find there. Or even in Latin America
