Shaunna MorrisonDr. Sara Walker of ASU is an astrobiologist and theoretical physicist interested in the origin of life and how to find life on other worlds. She presented on "Planetary systems biochemistry - inferring the laws of life at a global scale."
Currently we do not know what life is, or whether there exist universal laws - in the same sense the laws of physics and chemistry are universal - that describe life. If we could understand the fundamental physics of life it would be possible to not only engineer the creation of de novo life in the lab, but also to provide better quantitative methods for identifying life on other worlds. In this talk I discuss new approaches to understanding what universal principles might underlie living matter, based on studying biochemical networks on Earth from the scale of individual organisms to the planetary scale.
