I am a geochemist and geobiologist interested in understanding how interactions among the solid Earth, surface environments, and the biosphere have shaped our planet through deep time. My research combines isotope and elemental geochemistry with sedimentology, stratigraphy, and palaeontology to reconstruct changes in continental weathering, ocean chemistry, redox conditions, and global biogeochemical cycles.
I joined TES as a three-year postdoctoral researcher at Adelaide University in 2026, where my current research focuses on the Palaeo–Mesoproterozoic geology and geochemistry of the Bangemall Supergroup in Western Australia and broadly coeval sedimentary successions in India. I aim to use integrated geological and geochemical approaches to better understand how tectonics, continental weathering, ocean chemistry, nutrient cycling, and marine redox conditions evolved during this important interval of Earth history.
Before joining Adelaide University, I conducted postdoctoral research at the University of Maryland and George Mason University in the United States. Much of my previous research has focused on major environmental and biological transitions during the Neoproterozoic and early Phanerozoic. I use multiple isotope systems, particularly Li, U, Sr, Tl, and Cd isotopes, together with conventional stable isotopes and trace-element geochemistry, to investigate the connections among continental weathering, ocean oxygenation, carbon cycling, climate change, and biological innovation.
My previous work has explored Earth-system changes associated with the Cryogenian Snowball Earth and its aftermath, the Ediacaran Shuram Excursion, and the Ediacaran–Cambrian transition. I am particularly interested in how continental weathering and ocean redox evolved across these major transitions and how these environmental changes may have influenced the emergence and diversification of complex life.
More broadly, my research seeks to connect geological observations with geochemical records across different spatial and temporal scales. At Adelaide University, I am excited to extend this approach further back into the Palaeo–Mesoproterozoic and explore how long-term changes in tectonics, weathering, ocean chemistry, and nutrient availability contributed to the evolution of the Earth system and ultimately set the stage for later biological innovation.
