What to do after PhD?
In the sciences, it is almost expected if you want to go into academia that you will do at least one postdoc.  (In some disciplines like astrophysics, you might even do more than one!)  There are a lot of different job boards out there for finding a postdoc, but your best source (assuming you are still on speaking terms) is your thesis advisor.  He/she will likely have friends and colleagues looking for a postdoc.  Those folks will then know the background you are coming from and likely put you on their short list.  Good luck!
