I'm not quite sure whether this is the correct subforum in which to post, but here goes. I have a had a wonderful first year in grad school excepting the following interactions with one of my Professors. I do not mean to whine, and I honestly don't believe that professors have enough time to truly hate a student, but I am a little puzzled about resolving a rocky relationship with one professor in the department who works in the field I want to go into. It seems that this professor goes out of her/his way to avoid avoid any interaction with me, even to the point of turning around in an empty hallway, avoiding me after talks and sundry other incidents. I might chalk this up to a shy personality were it not for my observations of this professors interactions with other students, which are generally quite warm. I don't want to catalogue my past interactions with this professor, but I wonder whether I may have offended her/him at some point. I am asking if anyone has any similar experiences, and suggestions on how to resolve this situation. I don't want to accuse this professor of anything, but I would like to feel comfortable in my interactions with her/him.
