Im a graduate student in my 3rd year studying theoretical plasma physics. I'd like to stay in academia but I think I would be better in an area of experimental physics where data analysis plays a more important role (such as High Energy Experiment). I wanted to know wether or not it was possible to get a postdoc in another field than the one I write my thesis in. I'd like to hear from anyone who has done this.
If this is a possibility (a realistic one), what can I do to prepare myself in the remaining 3 years of graduate school? Thanks!
