Thanks all for your suggestions!! I have taken @cloudyword's advice, and kind of created a document with potential schools, a few professors of interest per school, and a summary of their featured publications.
I've now just been reading publications, and adding them to my document. It's a lot of work, and it takes a lot of time, but I guess that's how you do it! Lately, all I've been thinking about are PhD applications and the GRE. School resumes on Monday. AAAH!!
