Congrats on getting an interview with Kwan! ASU has a very cool program and I would love to live there... Baumeister is a monster in psych as a whole-- even my boss in clinical knows his work and he is ranked #7 in cumulative impact of current social faculty. He has so many different ideas going on that relate to a number of areas. Here is what I was told when I consulted a friend who is a social psychologist concerning my original list of POIs.
"You have some heavy hitters on your list. Roy Baumeister and Arie Kruglanski arehuge figures in social psych. If you were to interview with one of the more senior,highly productive professors, you might consider asking (either the professor orhis/her current grad students) how much face time you could expect to have. Sometimes the more senior people don't have a lot of time for new grad students soit can be a good fit for someone coming in with a Masters, but maybe not the bestfit for someone coming with a BA who will need more one-on-one training in thebeginning"I proceeded to place my focus more on other people that I liked at those schools. It would be awesome if you pulled off an interview with him. I just didn't know if I would have a shot at all.
