Let's say you've been a post-doc for nearing six months....is it still OK to give a job talk based on your PhD research? If you do decide to give a talk based on your PhD, should you throw in a few slides mentioning what you are doing now? What if the post-doc research isn't methodologically or thematically related to the rest of the talk?
There's no way I can give a whole 45+ minute talk on my post-doc research - I don't have anywhere near the data analysis completed that I would need. I could give 5-10 minutes about the experimental set-up and preliminary results, but it doesn't connect with the rest of my nicely coherent PhD talk.
If you were me, what would you do? If you were on the search committee, what would you think about a candidate who gave their PhD work rather than in-progress post-doc work?
