Dr. Lewis Walden serves as a Lecturer in the School of Molecular and Life Sciences within the Faculty of Science and Engineering at Curtin University. He holds a Bachelor of Science in Environmental Science with Honours and a Doctor of Philosophy in Environmental Science. As an active researcher in the Soil and Landscape Science Lab, Walden's work focuses on soil carbon monitoring, soil health assessment, revegetation practices, carbon sequestration potential, and the effects of drought and wildfire disturbances on forest ecosystems and soil properties. He utilizes mid-infrared spectroscopy, deep transfer learning models, remote sensing technologies, and environmental drivers analysis to study soil organic carbon fractions, bacterial and fungal richness, blue carbon ecosystems, and rangeland soils. Walden contributes to projects advancing spectroscopic characterization of soils for mine site rehabilitation and provenance determination of coastal marine soils.
Walden's scholarly output includes impactful publications such as 'Deep transfer learning of global spectra for local soil carbon monitoring' in the ISPRS Journal of Photogrammetry and Remote Sensing (2022), which has garnered 87 citations; 'How much organic carbon could the soil store? The carbon sequestration potential of Australian soil' in Global Change Biology (2024, 39 citations); 'Multi-scale mapping of Australia’s terrestrial and blue carbon stocks and their continental and bioregional drivers' in Communications Earth & Environment (2023, 21 citations); 'Drought then wildfire reveals a compound disturbance in a resprouting forest' in Ecological Applications (2023, 21 citations); 'Carbon consequences of drought differ in forests that resprout' in Global Change Biology (2019, 32 citations); 'Eucalyptus reforestation induces soil water repellency' in Soil Research (2015, 46 citations); 'Miniaturised visible and near-infrared spectrometers for assessing soil health indicators in mine site rehabilitation' in Soil (2022, 22 citations); 'FT-MIR Spectroscopic Analysis of the Organic Carbon Fractions in Australian Mineral Soils' (2025); and 'Mid-infrared spectroscopy determines the provenance of coastal marine soils and their organic and inorganic carbon content' (2024). With over 348 citations documented on Google Scholar, his research supports conservation efforts, climate mitigation strategies, and land management in Australia. Walden also supervises postgraduate research on topics like spectroscopic characterisation of blue carbon soils and collaborates internationally, including visits to Zhejiang University.
