I am a master's student in theoretical physics currently in my final semester in Germany. My master's thesis is already underway, and I aim to complete it by April next year. Recently, my partner and I have discussed my future job prospects, and I am interested in the possibility of continuing my research as a PhD within my current research group.
I am relatively new to academia and would appreciate advice on how to approach the idea of pursuing a PhD within the same research group with my supervisor(who is not the professor of the group) where I am working on my master's thesis. Specifically, I'm seeking guidance on increasing my chances of securing a Ph.D. opportunity within this group. Any tips or insights would be greatly appreciated.
