About
Lucas Demaret is a planetary geoscientist whose research focuses on the detection and quantification of organic and mineral phases using Raman spectroscopy, primarily to support robotic exploration missions on Mars. His major contributions include developing analytical strategies for representative subsampling and quantitative analysis of organo-mineral solid dispersions, demonstrating that the relative proportions of minerals in binary mixtures can be accurately determined using Raman scattering coefficients. He has also advanced the understanding of clay mineralogy on Mars, particularly the challenges and possibilities of analyzing Al- and Fe/Mg-rich clays, which are key indicators of past aqueous environments. Demaret’s work on Fe-rich fossil vents as Mars analog samples has provided critical insights into identifying extinct hydrothermal chimneys, linking mineral deposits to potential biosignatures. His most-cited papers, with 5–8 citations each, have established foundational methods for in-situ planetary spectroscopy. Notably, his research bridges laboratory calibration with the practical constraints of robotic missions, enabling more reliable detection of organic compounds like β-carotene and L-cysteine in gypsum matrices, a crucial step toward searching for signs of life beyond Earth.
