Answer

Everything is fine, in my opinion, except for the last sentence. 

You no longer need to be recommended (in the sense - as worthy to hold a position or worthy to defend) since you have already been accepted as a candidate to defend your dissertation. 

If you are using "recommend" to mean "present as worthy" the sentence should read: 
So, I recommend him to you FOR the defense of his dissertation. 

or more formally, 
So, I recommend him to you (my distinguished collegues)* for the defense of his dissertation. 

* the committee of professors who are judging your defense.
