Over the past two years, I've been collaborating with a PhD student. He did experimental work, and I did modeling and data analysis based on his experiments. Now that my colleague is about to write up his PhD thesis, in which way can he ethically include the modeling and data analysis results in his thesis?
I don't need any of these results for a thesis on my own, and we are currently writing a paper on this together, so there are no worries from my side about misuse of these results.
There is the related question Are overlapping dissertations ethically acceptable?, but I am more explicitly asking about how my colleague can present the results which are more based on my work in a good way.
