The postdoctoral program is small so a lot of attention is given to each person. The labs are also small (2-4 people). Publications are encouraged. It is a good opportunity to evaluate going into industry or finding a job in academia.
What I wish was different
There is not so much training. As a new graduate you need to train yourself quickly.
I recommend GNF to anybody. Working here gives you an opportunity to do cutting-edge research. You have a lot of funding and people like to collaborate.
