I decided to pursue a PhD degree after a few years in industry, so I contacted a professor from the university where I had received my Diploma a few years back. We had some conversations, she was rather positive as I had good grades and I used to attend her lectures. I could not apply officially yet, since the PhD applications start during summer. As coronavirus came, we all stopped going to the lab.
I emailed the professor about 10 days ago about how to proceed. However, I did not get any answer. Is it possible that she changed her mind about having me work in the team as a PhD candidate, since we had no communication for around 1 month?
