I am admitted to a UK university for my PhD and I am supposed to submit a proposal for the PhD topic. I reached out to a professor and he responded saying that he is interested in discussing it further and asked if I had funding. Since I am already a student there, I replied saying I am funded, however he hasnt replied to me in 2 weeks. I am getting anxious as the deadline is nearing for the submission of the proposal. I sent a follow up email (in-case my previous mail was lost).
Should I consider this as a rejection, or wait for him to respond (considering he is one of the top scientists in his field and he might be busy) or move on to another professor?
I dont want to be rude by showing up in his office or calling him.
