I was admitted to the PhD program at the beginning of the Fall semester and I chose this particular school because my current adviser was my first choice. My admission letter states that they will fund me for the duration of my studies.
Now my adviser tells me the funding source he applied for to cover my stipend and tuition did not pan out and he wants me change my adviser to a different professor.
I do not want to change advisers. As I said, I chose my current adviser over several other good choices. Can I refuse his attempts to make me switch advisers?
FYI, the school traditionally covers funding where external grants are lacking.
