thanks. so i think i should try to do biophysics research! i.e. i noticed a professor in 1 of our depts is doing this thing with lasers(tweezers). otherwise, if i just do pure math, im afraid i wont be able to answer the question "how is your research relevant to dentistry?"
but i plan to do research only starting next summer(after my junior year). And i wonder if i should email that professor and ask him if i could do anything/take appropriate courses so that i could later have chances to do research in his lab, or it's a bad tone to bother professors like this? and im afraid if i cant do research in his lab, i'll be really messed up, because i dont have enough physics or biology to be doing any research in any other labs that i looked at.
