I'm almost sure that she's not a scientist. Most likely just a fat trying to fit in. "Teehee look at how much of a nerd I am!! Go science!!" I volunteered in a cancer research lab and was friends with just about every scientist there. There were no obeasts and the only people slightly overweight were 50+ year old moms. Granted I'm Canadian (and live in an area with not too many fats in general), but I can't imagine there would be too many obese intellectuals.
