A question of formality?

I'm revising a text and it's a non-native writing in English. She prefers to use "of" than phrasing with inversions, and it's making me uneasy. I don't know if it's preferable in a formal context (it's a doctoral thesis). For example, "the revision of this thesis", instead of "this thesis revision", and "the sections of this thesis", instead of "this thesis sections". Can anybody help me?
