[When/how to pick research topic]

Thank you both. This helps a lot.

Yes, I am required to do 3 rotations with the option of adding a 4th.

I especially like what you said, samman1994, about why you even got into biochem in the first place. I'll try to keep that in mind while I read.

[When/how to pick research topic]

I'm going into an ecology and evolution PhD program in the US this fall. I don't have a specific project in mind yet. I just know that I'm interested in how human activity affects the makeup and distribution of microbial communities. All these other people keep telling me all about what they're going to work on once they start graduate school. I feel so lost and inferior. I keep thinking that I seriously messed up, but I thought I had at least a year before I needed to come up with my project. Was I wrong? How do I pick a topic? Do you have any specific reading suggestions for my interests?

Thank you.
