Is it possible to do a Master's and PhD at the same time? I am currently in my master's and about to start my research. Is it possible that I can do my research with any institute in Europe or do my Ph.D. at the same time but from different universities?
In most European countries you can be considered for a PhD position only if you have already a master in a related field. 

I also think that doing a master and a PhD at the same time will be too much work for one person.
