“The problem with attempts to define life is that life is not a natural kind.”

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 currently Deputy Director of the Beyond Center for Fundamental Concepts in Science at Arizona State University, Associate Director of the ASU-SFI Center for Biosocial Complex Systems and an associate professor at Arizona State University (ASU). She is an advocate for the communication of science to the public, and has participated in many interviews, panels, and lectures to discuss her research and topics related to her fields of study.
