The case for making doctoral supervision collaborative In the course of my research career, I have written relatively extensively on the topic of food, but only now have I realised that the consumption of food can be extended to the consumption of knowledge. In a recent paper entitled “Doctoral supervision challenges: What do we know and what can we do about it?”, which I presented at the sixth annual online Researcher Education and Development Scholarship (REDS) conference organised by the University of Leeds in the United Kingdom, I highlighted a three-point challenge for the PhD supervision experience: recruitment, retention/progression and completion, which I would map to the phases of a three-course meal – the entrée/appetiser, main course and dessert.
