About
Dr. Laura M. Barge is a pioneering astrobiologist and geochemist whose research bridges the origins of life, planetary science, and autonomous instrumentation. Her key contributions lie in understanding how chemical energy gradients in hydrothermal systems could drive the emergence of life, and in developing robotic platforms for in situ planetary exploration. Dr. Barge is best known for her experimental work on electrochemical gradients in simulated hydrothermal chimneys, demonstrating how mineral catalysts can facilitate organic synthesis—a foundational step toward life’s origin. Her highly cited studies on chemiosmotic coupling and protometabolism have reshaped models of prebiotic chemistry, earning over 2,000 citations. Notably, she leads the design of autonomous Raman spectrometers for Mars rovers and deep-sea landers, integrating convolutional neural networks to interpret spectral data in real time. Her recent 2025 paper on CNNs for Raman spectroscopy, though early in citation count, exemplifies her innovative fusion of geochemistry and machine learning. Dr. Barge’s work has been recognized with NASA’s Early Career Award and a prominent role in the Ocean Worlds Exploration Program. For students, her research offers a compelling vision of how chemistry, robotics, and artificial intelligence converge to explore life’s origins—both on Earth and beyond.
