معرفی
Dr. Alexandra Turchyn is a researcher at the Department of Earth Sciences, University of Cambridge. Her work focuses on isotope geochemistry and biogeochemical cycles, particularly through sedimentary processes and carbon-sulfur-iron interactions. She supervises projects related to global biogeochemical cycles, submarine basalt weathering, sedimentary diagenesis, and geomicrobiology.
- Key research tools: stable isotope mass spectrometers
- Recent interests: calcium and strontium isotopes in sedimentary systems
- Methodological innovation: reactive transport modeling for subsurface process quantification
Her group investigates how planetary environments evolve through isotopic, chemical, and mineralogical analyses of modern and ancient sediments, pore fluids, and rocks. Current projects include development of new methods for gas isotope ratio measurements in SO2 and CO2 using advanced laboratory equipment.
Major research themes include:
- Carbon cycle evolution across Earth history
- Climate change reconstruction through geochemical proxies
- Subsurface biogeochemical processes
- Isotope fractionation in natural systems
