Hello, I am currently a EEE junior year student in an International University. I am looking to shift fields to a more Physics oriented field in my Masters/Phd, something along the lines of Plasma Physics/ Optics/ Accelerator Physics etc The thing is I have come across a quite renowned professor and I feel I have a good chance of working with him if I proceed as I have been talking with him for a while. But the catch is that he is a Mathematical Physicist and works on String Theory and stuff. He takes a good number of EEE students from top Uni here to help them switch fields and go into Theoretical Physics. But the thing is I don't want to go into "Pure Theoritical Physics" for Grad School, but more along the line I mentioned earlier, but I do want to work on the more theoretical aspects of those fields. So would it be wise to take up this opportunity and work with him, if I do get the chance? I feel I lack the required Mathematical Background to work with him, but I hope I can make it up in time should it be afforded. I should also mention that he's by far more renowned that any Professor in our University. So I guess that working with him will also help me get a good Letter of rec. if I don't blow it up. So what should I do? I hope I am not too vague. Thanks everyone!!
