 Sara Walker is featured in an article on Space.com highlighting the role of theoretical physics in helping discover alien life.
"When I think about looking for life, I'm not really thinking about looking for cells on a planet or molecules in an atmosphere. I think about looking for an entirely new sector of physics," Sara Walker, an astrobiologist and theoretical physicist at Arizona State University, said during a panel discussion at the World Science Festival in New York City.

A new, seven part animated series explores the lasting impact of Mary Shelley's Frankenstein. Episode two explores the topic "What is life?" and features our own Sara Walker! The episode is below, other episodes in the series are available here.
Video of the World Science Festival panel "Who is Out There: Why Alien 'Life' may be Weirder than we Imagine" is now available! The panel features Sara Walker, along with astronaut Nicole Stott, astronomer Lisa Katlenegger, astrobiologist Caleb Scharf, and philosopher Susan Schneider. Check it out at the link below!
For the next three days (June 4-6), Sara Walker and Harrison Smith will be attending the 4D Workshop: Deep-time Data Driven Discovery and the Evolution of Earth. This unique interdisciplinary workshop focuses on a data-driven approach to understanding the history of our biosphere. Using big data analysis techniques such as network theory, the workshop addresses the following questions:
 Carbon mineral-locality network. Mineral nodes colored by age (Ma) and sized by frequency of occurrence on Earth’s surface; locality nodes (black) sized by mineral diversity. (Image source: https://www.4d-workshop.net/about) |
