My PhD supervisor wanted me to talk about how my research was "validated" by another student in my Viva Voce, despite my results speaking for themselves. This part of my findings had not even been questioned by my examiners.
The student in question had never worked with me in any way. Nor have they published in a work I could cite - conference paper, article or even blog post. Or even private correspondence.
He claims it is common to "have worked with people in this way".
I don't understand why he would ask me to do this.
I am asking this question from the perspective of the exam administration. Isn't it cause for concern to bring up a person who wasn't cited or acknowledged in the thesis during the Viva?
