Scientific collaboration on research conducted as part of a doctoral programme can take various forms that may or may not result in the awarding of a PhD from UCL.
In the context of a PhD undertaken at UCL, students will be able to benefit from scientific collaboration of quality and depth thanks to the various members of their supervisory panel, each of whom can point students towards specific areas of research and open up networking opportunities for them.
Whether or not you are a PhD student enrolled at UCL, the scope of scientific collaboration can also be expanded through joint thesis supervision (without undertaking a joint degree programme); this means that you pursue doctoral studies at one university but have access to the more specific expertise of two official thesis supervisors. This type of collaboration often involves spending some time at the university of the second supervisor for the purpose of scientific research and/or training.
Another way of strengthening scientific collaboration is by undertaking a joint doctoral programme (as part of a joint degree programme); this involves pursuing full doctoral studies on the same research at two universities. With this option, you will receive a double degree, one from each of the institutions in question.
There is no ‘right’ solution, as each has its own merits. The best kind of scientific collaboration for you will be whatever best suits your research and doctoral training.
