I hold a Bachelor in physics and I am applying for a master program in Germany. There is a research group by a professor, with topics very close to what I'd like to study and furthermore work on. On the group's site it is posted that there are open master-phd positions.
Should I email the professor, expressing my willingness to study and possibly work in the future under his group if I am not yet admitted to the program?
My email would contain some basic information about my choices of classes, bachelor thesis, personal studies after my bachelor and interests in the research group.
