After the whole summer struggling, I successfully passed the qualify exams. So I have to figure out what to work on in my PhD study. If you have any suggestions, please let me know.

1, What inspired you to work on… whatever you work on?

Grad students often wonder how people get ideas of things to work on. The usual advice I give is (1) go to talks, (2) read papers, (3) talk to people, (4) follow through on all of the above.
