I am preparing the final document of my PhD and I would like to include some kind of identifier to my person – something like a DOI for people. My intention is to to make it easy for the readers of my thesis to get in touch with me and to have a look at my other work. As I don't know at what university I will work in the future, it shouldn't be something related to my current university.
I feel like ORCiD or Google Scholar could be good options, but there are many others out there, such as Mendeley, Scopus, etc. However, I would prefer to include only one or two links. What are the most professional, persistent, and commonly used researcher profiles in academia?
