Dear babi,

thanks for your thorough contribution.It seems you are majoring in Teaching too.A great luck!
As you may find most of freinds in this forum have consensus on Tehran university.
I know only Dr farhadi and keshavarz as prominent figures in this field but they are teaching in the other places.
You seem to know proffesors much better,so do me another favour and tell except for these 2 which of your aforementioned ones are the most famous.

Best
