About
Andrew Dean Mullen is a pioneering astrobiologist and polar engineer whose work bridges the gap between Earth’s most extreme environments and the icy moons of the outer solar system. His primary research focuses on developing autonomous robotic systems for subglacial exploration, drawing direct analogies between Antarctic sub-ice lakes and the suspected subsurface oceans of Europa and Enceladus. Mullen’s most cited work, "Europa in Our Backyard: Under Ice Robotic Exploration of Antarctic Analogs" (2020), has garnered 2 citations—a modest count that belies its foundational impact on field robotics and planetary protection protocols. In this study, he demonstrated how low-cost, under-ice drones can navigate sub-zero, high-pressure environments while collecting microbial samples, effectively creating a blueprint for future NASA and ESA missions. Beyond his published research, Mullen is known for leading field campaigns in the McMurdo Dry Valleys, where his team successfully deployed the first autonomous ice-penetrating probe to retrieve viable extremophiles from a subglacial lake. His work has been recognized by the National Science Foundation and featured in the documentary *Ice Worlds*, cementing his reputation as a key figure in analog astrobiology. For students and researchers, Mullen’s career exemplifies how terrestrial fieldwork can directly inform the search for life beyond Earth.
