Sara Imari Walker

Sara Imari Walker leads one of the largest international theory groups in origins of life and astrobiology. Walker and her team's key areas of research are in developing new approaches to the problem of understanding universal features of life; those that might allow a general theory for solving the matter to life transition, detecting alien life and designing synthetic life. Applying assembly theory, a physics framework based on molecular complexity that Walker and her team have expanded, opens a new path to identify where the threshold lies where life arises from non-life, and to detect and understand the evolution of life on our planet and in the universe.
