I will be applying to PhD statistics programs this upcoming fall and really enjoy statistics. But, I also love physics (started as a physics major) and am wondering if there is opportunity post-PhD to work in a physics (or astronomy) department. I am aware of some programs (such as CMU) that do research in astrostatistics and some of those professors got PhD's in physics or astronomy, but did not know if it was possible to do the opposite.
I honestly cannot give a good reason why I ended up switching from physics to math, but do not take this as regretting it, I love math and especially statistics.
