Doing a PhD can be sometimes very challenging and this is accompanied also by high-stress levels. Sometimes, a PhD project is more difficult than others and in this case, the support of guidance is needed. This is the role of the supervisor, who should direct and help an early-stage scientist through this path. However, not always things go as they should. Often there can be misunderstandings between the supervisor and the fellow, leading even to a toxic relationship because of which - at the end - the PhD student either survives on his/ her own - with a great deal of stress accumulation - or he/ she reaches a point beyond which it is impossible to go on without the lack of any support and decides to give up. PhD students are characterised by an extremely high-stress level and even suicidal tendencies. What if we could develop a platform where PhD supervisors are reviewed? This, on the one hand, may help the PhD students to decide whether to go to a certain lab or not and on the other hand, it may also make more aware the supervisors themself - but also the all scientific community - that not only papers matter but also the quality of the supervision as well as the psychological welfare of the PhD students.
