Ross Eustace Geller (David Schwimmer) is a paleontologist at a museum of prehistory, and later a professor of paleontology at New York University. Considered by some to be the most intelligent of the six main characters, but at the same time a clumsy, quirky man, Ross is known for being a smart, know-it-all who prides himself on his rationality, despite his clear hopeless romanticism. He is shown to be the most caring of all the six members in the various instances on the show.
