So I have been in an EE PhD program for about 7 months and I am feeling uninterested in my current research field. I think I could be much more productive if I had a passion for my research. I am considering switching research groups. How should I go about this in a tactful way without losing funding or getting my advisor upset? Should I bring my concerns to my advisor's attention now or should I find a different professor first and then talk to my current advisor? How do you think I should handle this difficult situation?
