There are a lot of oppertunities for PhD Positions (Studentship, Fellowship, Fullbright Scholarship, Commonwealth Scholarship, German Scholarship, Cultural Exchange Program, etc). And there are so many group leadres seeking PhD fellows all around the world.
So, why are you making yourself too limited to a Professor who is going to be retired soon!!!!
Search for any other!!!
Wish you good luck!!

PhD thesis, Methodology Chapter should be written in Past tense (preferably in passive voice).
