A potential suprvisor (British university) gave me a positive response after my first email, and asked me to send a more detailed research proposal to him. I send it to him on the 14th of July, and only received an automatic response from him.
I will be back after 18th of July.
When time went to August, I still did not receive any response from him, so I sent him a follow-up email on the 3rd of August, but did not receive a reply yet, what should I do now?
