Sara Walker is an astrobiologist and theoretical physicist interested in the origin of life and how to find life on other worlds. She is most interested in whether or not there are “laws of life’ related to how information structures the physical world that could universally describe life here on Earth and on other planets. Walker is deputy director of the pioneering Beyond Center for Fundamental Concepts in Science, which is devoted to confronting the big questions of science and philosophy. She is Associate Director of the ASU-Santa Fe Institute Center for Biosocial Complex Systems and Assistant Professor in the School of Earth and Space Exploration. She is also Co-founder of the astrobiology-themed social website SAGANet.org, and is a member of the Board of Directors of Blue Marble Space. She is active in public engagement in science, with appearances at the World Science Festival and on "Through the Wormhole" and NPR's Science Friday.
