I am a PhD student in stochastic analysis/control and had a MSc degree in Financial Mathematics. 

I am interested in determining there is a quantitative finance ranking system for universities like [this](http://en.wikipedia.org/wiki/QS_World_University_Rankings). It's easy to find such a ranking for the Math Universities, though it doesn't hold for the quantitative/financial mathematics field.

Does such a ranking system exist, or is there another ranking system that can be applied to universities and quantitative finance -- and if so, how?
