Research interests

My research centres on developing tools for studying environmental systems in situ, especially passive sensor-based approaches. Techniques combine geophysical and electrochemical methods with time series analysis and multivariate statistics. Focus on energy transduction and biogeochemical sycling of metals, carbon, nitrogen, and sulfur. Applications include astrobiology and life detection, agricultural and environmental monitoring, and environmental remediation.
