About

Alexa Drew is an astrobiologist whose work bridges the gap between planetary science and biochemistry, focusing on how life might arise and persist beyond Earth. Her most-cited paper, "Seeding Biochemistry on Other Worlds: Enceladus as a Case Study" (2020, 16 citations), tackles a fundamental challenge in the search for extraterrestrial life: the lack of quantitative frameworks to assess the chemical possibilities in alien environments. By using Saturn’s moon Enceladus as a model, Drew develops tools to map the chemical space accessible to life, offering a systematic way to evaluate biosignatures and prebiotic potential in ocean worlds. This work is pivotal as missions like Europa Clipper and Dragonfly prepare to explore icy moons. Drew’s research not only advances our understanding of where to look for life but also provides the theoretical scaffolding needed to interpret what we might find. Her contributions are shaping the next generation of astrobiology, making her a key voice in the quest to determine if we are alone in the universe.
