Academia's view on body modification
You will likely be judged differently in any situation, where you have to be present in person - that is, all kind of interviews (actually even via skype and similar).

Your skills become more important later in your academic life, but the documented skills of say a master student who applies for a PhD position are very limited - personal judgement plays the major role here.

Therefore, you might want to wait until you do a PhD, or even after that. By that time your publications and achievements may speak for themselves and all you need to do is to find a PI that is okay with your looks.
