Astrobiology seeks to answer the age-old questions "Are we alone?" and "Where did we come from?" To advance these queries, my research takes on a unique blend of planetary science, data science, and philosophy. This talk will cover four of my most exciting projects. First, I will explore how the topologies of atmospheric chemical reaction networks of Solar System bodies are distinct from one another, with potential applications to exoplanet biosignatures. Second, I will show how we can look for in-situ biosignatures by combining pyrolysis–GC–MS measurements of a wide variety of terrestrial and extraterrestrial carbonaceous materials with machine learning, achieving >90% accuracy in the differentiation between samples of abiotic origins vs. biotic specimens. Third, I will propose a new time-asymmetric law that states that the functional information of a system will increase over time when subjected to selection for function(s). And finally, I will introduce four novel principles of "astrobioethics" that can serve to guide our future investigations of extraterrestrial environments.
TSI Seminars take place weekly during the Fall and Winter terms. TSI seminars are intended to be accessible to scientists from the entire breadth of backgrounds at TSI, including, Physics, Planetary Science, Geology, Atmospheric Science, and Astrobiology. Our seminar series is partially funded by the Centre de recherche en astrophysique du Québec (CRAQ).
