I just got into the mechanical engineering PhD program at my school and I am slightly confused about the best way to choose a PhD adviser. I am currently working with a professor from undergrad research that I would like to stay with, but he is not 100% confident about funding... Do all grad students typically get funded by their professors for research? Is the "popularity" of your professor in the field a big deal? Would an older, more experienced, and possibly more respected professor be a better PhD adviser? Should I just choose the professor who's research I enjoy the most, and not worry about funding or anything else? I still have time to pick my adviser, so if anyone has any advice on the matter that would be awesome. Thanks!
