In the following sentence, should the preposition be "on", "of", or "for" after the noun phrase "institute"?<br/><br/>"We are a premier training institute <u><i><b>on </b></i></u>investigation and forensics, in the region and beyond."<br/><br/>I have another question regarding the sentence: is "beyond" idiomatic in the propositional phrase?<br/><br/>Thank you for your help.
