Dr. Walker is an astrobiologist and theoretical physicist at Arizona State University, where she explores the origins of life, artificial life, and the detection of life on other worlds. At ASU, she has built a highly interdisciplinary research program and leads one of the largest theory groups in origins of life and astrobiology internationally. Her latest book Life as No One Knows It: The Physics of Life’s Emergence proposes an answer to the age-old question, “What is life?” Sara joins the podcast to explain how the search for alien life is related to the origins of life and whether we are more likely to find microbes on other planets or intelligent life.
