i have heard so many cases of research robbery thing.
even back-stabbing.

advise: once u got whatever good finding, present it straight away to your
supervisor. =)

furthermore, that robber will faced trouble in order to write the paper for the conference. believe me

ahaha if knife is used, i cant post this comment. dead lol

in normal practice, researches done by using money (grants) or rather information by the supervisor. so no issue of 'supervisor robbing'
