Including Results in Dissertation Before Publication in a Journal I am in the final phase of my Ph.D. research. I need to defend my thesis before my fellowship funding runs out in a few months. 

I won't have time to carefully prepare and polish my results for journal papers before I defend. I need to include some preliminary, unpublished results in my thesis, as per the work I agreed to do in my thesis proposal. 

But is submitting results (to a journal) that are already "published" in my Ph.D. thesis an issue? One issue I'm wondering about: journals run a "plagiarism" check, and I wonder if "self-plagiarism" will be an issue.
Good question! No, your thesis does not count as published (yay). Self-plagiarism is definitely not an issue here. Good on you for clarifying though!
