Lisa Messeri completed her dissertation at the Massachusetts Institute of Technology’s Doctoral Program in Science and Technology Studies in September 2011. She is working on a manuscript entitled Placing Outer Space: An Earthly Ethnography of Other Worlds, concerning the role of place in scientific practice and how ideas of place shape and are shaped by science. Previous research on the cultural stakes of “planet,” as made clear by Pluto’s 2006 reclassification has been published in the Social Studies of Science. Messeri is presently a Fellow at the University of Pennsylvania.
