Peter Agre, who completed clinical training at Case Western Reserve School of Medicine, discovered aquaporins, or proteins that form pores in cell membranes and allow for the movement of water through them. Agre shared the 2003 Nobel Prize in Chemistry for his work, which disproved assumptions that water leaked through a cell membrane. (The previously held consensus did not account for the rapid movement of water through some cells.) Agre was president of the American Association for the Advancement of Science from 2009 to 2011.
