About
Stephanie Gandulla is a leading astrobiologist whose research bridges Earth’s most extreme microbial ecosystems with the search for life beyond our planet. Her work centers on microbial mats and microbialites—layered, sediment-bound communities that represent some of the oldest known life forms on Earth. Gandulla’s key contribution lies in using these extant structures as direct analogs for potential extraterrestrial life, particularly in the subsurface oceans of icy moons like Europa and Enceladus. Her most cited paper, “Extant Earthly Microbial Mats and Microbialites as Models for Exploration of Life in Extraterrestrial Mat Worlds” (2021), has garnered significant attention for its novel framework that reframes aquatic, water-dominated worlds as prime targets for biosignature detection. By demonstrating how benthic microbial communities thrive in extreme conditions—high salinity, low light, and chemical gradients—Gandulla provides mission planners with concrete models for what to look for on other worlds. Her work is foundational for NASA’s astrobiology roadmap, influencing both instrument design and sampling strategies. With a growing citation record, Gandulla is recognized as a rising voice in the field, merging field microbiology with planetary science to answer one of humanity’s deepest questions: are we alone?
