I am a second year PhD student. I am still in the process of finding a research topic. I have a couple research ideas at early stages with two different professors.
I will be in another country for two weeks, for personal reasons. I want to meet with several professors when I am there. First, I believe it is a good opportunity to network. Second, there are a couple professors with very interesting research areas and I can see myself working on one of these areas.
Since I do not have a concrete research area, is it still a good idea to meet with them? How can I make sure that they will not feel like I wasted their time?
