Contacting professors for PhD vacancies
I will be applying for PhD programs (particularly TCS) for Fall, 2013. Should I personally try contact advisors for this purpose? At some universities, there are multiple faculties whom I want to work with. If I don't contact them then am I at a disadvantage? What should I write about if I should contact them? Any other advice is appreciable.
I am sorry if this sounds a stupid question or not a real question but since many of the users are here themselves faculty and PhD students, I thought it to be the best place to ask this question.
